<description>Feeding pattern, nutritional status and common diseases of under two years children attending at outpatient department of a tertiary level hospital
Zannat, Mst. Nur-A-
This cross-sectional study was conducted to assess the feeding pattern, nutritional condition, and prevalence of common diseases among children aged 0 to 24 months who come to take health services in outpatient department (OPD) of a tertiary hospital in Rajshahi, Bangladesh. The sample size was 467 which was selected purposively. Regarding the feeding pattern, our findings indicate that 54.8% of the women exclusively breastfed their children, 68.5% continued breastfeeding until the child reached the age of two, 52.7% weaned their children appropriately, and 57.4% continued to provide appropriate complementary feeding to their child's diet. Our study demonstrated that 28.3% of the participants had mild underweight, 26.1% had moderate underweight, and 5.1% had severe underweight in terms of their nutritional condition. On the other hand, 34.9% of the participants reported experiencing mild wasting, while 12.4% reported moderate wasting, and 4.5% reported severe wasting. It was revealed that 36.2% had mild stunting, 9.0% had moderate stunting and 4.1% had severe stunting. Regarding common diseases, 61.2% of individuals experienced symptoms of cough and cold, 21.2% were diagnosed with pneumonia, 12.2% suffered from diarrhoea, 4.3% had fever, and 1.1% were affected by other diseases. We found statistically significant relationship between occurrence of illness and feeding pattern (Exclusive breast feeding, breast feeding up to 2 years of age, proper weaning practice and appropriate complementary feeding). We also found statistically significant relationship between the occurrence of common diseases and nutritional status (Underweight, wasting and stunting). The observation was that, the practice of complementary feeding was not up to the satisfactory level. Maximum parents practiced inappropriate complementary feeding in which most of the cases did not include protein, fiber and minerals. The rate of severe malnutrition reduced but some extent of under nutrition had been observed. Thus inappropriate feeding practice and under nutrition affect the occurrence of common illness (ARI- Cough &amp; Cold, Pneumonia, Diarrhoea and Fever) which is the most important cause of death in children under two years old.&#13;
The goal of our study is to reduce childhood mortality and morbidity. However, this study optimizes the coverage of different intervention like promote nutritional status and educate parent for appropriate feeding practice to continue for lessening the prevalence of childhood illness.

<description>Effect of antioxidant on pesticide induced cytomorphological consequences in hexaploid wheat (triticum aestivum l.)
Akter, Afroja
To meet up the growing demand of huge number of population, high production of crop plants playing a major role in ensuring food security and food availability. But different kind of pests and diseases is affecting the production of crop plants adversely. Now-a-days pesticides have got a remarkable popularity in terms of pest management, plant protection and to increase the yield of the crop plants. Thus, crop plants are being directly affected with different sorts of adverse consequences. Mutagenic and carcinogenic effect of pesticides is managed by the use of antioxidant as it is used in case of mammals. The present study was designed to investigate the protective role of antioxidants against pesticide toxicity in wheat seeds. Wheat seeds treated with pesticides were used as control in this experiment and then pre- and post-treatment were operated using antioxidants. The seeds of pre- and post- treatment were designated as M1 generation. Treated seeds were allowed to germinate in laboratory as well as in the field following three factors randomized complete block design and data were collected on cytological as well as growth and yield related characters. The M2 seeds collected from M1 plants (raised from the seeds treated previously) were left untreated and were sown in next year. Again data were collected on morphological and cytological characters from M2 generation to investigate the residual effect. Result obtained from M1 generation indicates that pesticides induced adverse morphological and cytological characters. At the same time pre- and post-treatment of antioxidants showed positive effect on reducing pesticide toxicity enhancing growth and yield related characters. The overall findings indicated that antioxidants have an antagonistic effect against pesticide induced cytomorphological consequences. Result, also revealed that pre-treatment showed more efficiency than that of post-treatment. Result of M2 generation showed that both pesticide and antioxidant had same sort of residual effect.

<description>Improvement of bitter gourd (momordica charantia l.) Through breeding and biotechnology
Sikdar, Biswanath
A field experiment was carried out in the Fruit Research Station, Bindpur, Rajshahi during 2001-2003 with 6-pasestal and 5-parental diallel sets to determine the gone effects for different quantitative traits te, vegetative-reproductive and al traits in bitter gourd (Momordica charanis L.) Significant differences were observed for most of the traits. The range of variation was enough for all the traits studied, which showed greater scope for their selection as breeding materials. Varians analysis of diallel exhibited the presence of additive gene effects for most of the traits, except BBB, FBN, FEN, and ETS, PTS, GTT-LP, respectively for vegetative-reproductive and anatomical traits of 5-puntal diallel. Out of eighty-nine traits (in both dillelsets), the item was significant for 83 traits, opt ID, FPL, OD and FV of 6-pereal diallel and ID and FBN of 5-parental diallel. In this investigation, relatively lager value of 'a' component in comparison to those of '&amp;' for all the traits were observed. So, the additive component of variation was more important for all the traits in their inheritance.&#13;
The additive component 'D' was highly significant for all the traits, except LB12 and DRMF of 6-gatal diallel. Whereas, in 5-perectal dialled for vegetative- reproductive traits out of 35 traits the significant 'D' value was observed only for five traits (e, I, OL, FL, FD and FP. In anatomical traits the significant 'D' was observed in seven traits only. The item H1 was significant for most of the traits. The item 'D' was slightly more predominant in most of the traits than dominant component H. The components H, and F were significant for most of the traits and the values were also higher than their "D" values, which showed the importance of non-additive inheritance. It was observed that the H1 values were smaller than H, in most of the traits. So, equal frequency was present in the parents. The positive sign of Fin most of the traits indicated the presence of dominant genes, but in most of the traits it was non-significant, which indicated that dominant properties of genes was not valid. For most of the traits, was non-significant, epistis was not present in the pants.&#13;
In 6-parental diallel partial dominance was present in 19 out of 30 traits. Whereas,  most of the traits (24) showed over dominance in 5-parental diallel. Most of the traits indicated asymmetry of distribution with+,- alleles. In this experiment most of the traits exhibited excess dominant alleles Le, dominant alleles were more frequent than recessive alleles in punts in both of the diallel se&#13;
The presence of variability and non additive nature was noted for meat of the tits. The heritability in narrow sense ranged from 15.52 (LBL2) to 99.25% (FV) in 6- Parental diallel, 36.41 (DRB) to 69.35 (FV) and 1.40 (PTS) to 50.15% (OPT-IVB) respectively in vegetative-reproductive traits and anatomical traits in 5-allel The regression of Wr on Fr were unity in most of the traits and therefore, the additive dominance model was satisfactory. Non-allelic interaction was not observed in the parents&#13;
Combining ability was observed in 39 traits in both the diallel sets, GCA effects of parents and SCA effects in direct and reciprocal crosses were significant with a higher magnitude of C of GCA variance indicating that inheritance of these traits were predominantly governed by additive and additive x additive epistatic components. Among 6-paremal diallel of model-l method-ll, the genotype BGGBI was found to be the best general combiner for the important traits I, DRFF, FL, FV, FW and FFW. The genotypes BGGB4, BGGB13 and BGGB14 were the best the general combiner for DRMF, FNFW and HF/W respectively. Similarly 6-perectal diallel of model-l method-I showed th BGGB12 was the best general combiner for DRME, DRFF, FV, FW FFW and FNFW. For 5-parental diallel, the best performing GCA effect was in BOGB17 for IL, DRB, DRMP, DRFF, FL, FFT. The important traits FW, FFW, SF and FP had no significant general combiner. The parent BGGB20 was the best combiner for most of the anatomical&#13;
traits.&#13;
In the 6-parental dialled of model-l method-1, the best crosses with high SCA effects were BOOB14 x BOGB4 for DRMF BGGB6 x BOGB1 for DRFF, BOGB14 BGGB13 for FL, BGGBS BGGB4 for FD, BGGB14 BGGBI3 for FV, BGGB14x BGGB13 for FW, BOGB14 BOGBI3 for FFW, BOGB12 BOGB6 for HF/W, Similarly for 6-pantal dallel of model-t method-II the SCA effects showed that the best specific combinations were BGGB13 BGGB6 for DRMF, BGGB6 BGGB4 for DRFF, BGGB14 BOOB12 for FL, BOOB13 B0084 for FD, BOGB13 BOGBI for FV, BOGB12 BOGBI for FW, BGGB12 BGGB4 for FFW, BGGB13 x BGGBI for FNFW, and BGGB12 BGGB6 for HF/W&#13;
For 5-parenta Galle, the significant SCA effects were BGGB18 BGCB16 for DRMF, BOOB19 BGGB17 for DRFF, BOGB19 BOGB17 for FL, BOGB17 BGGB16 for FV, BOGB20BGGB19 for FFT and BGGB18 BOOB16 for SWF. For the traits HL, EL, LPL2, LBL2, LP, LBL, LBB, IL, FFN, OL, OW, SL, FD, FFW, SP and FP had no significant cresses. The best areas was BOOB 20x BOGB17 for most of the anatomical traits A high frequency of sprouting from shoot tips (90%) and nodal explants (93%) and shoot differentiation was observed in the primary culture of Momordica charantia L on MS hal medium supplemented with various concentrations and combinations of benzyl adenine (BAP), a-naphthalene acetic acid (NAA), indole-3-butyric acid (IBA) and gibberellic acid (GA). The best response in terms of single shoot formation was observed on MS medium with 2 mg1 BAP + 0.2 mgl NAA and multiple shoots were obtained by culture of shoot tips and nodal explants on MS with BAP (2 mg/l)+ IBA (0.2 ng)+GAs (0.3 mg). This combination was suitable for regeneration and growth of shoots. About 99% rating was obtained from shoots cultured on MS supplemented with IBA (0.6 mg/l). Pls with well developed roots were transferred to soil with survival frequency of 70%&#13;
The growth of meristem was observed on semisolid MS media when the culture media were supplemented with 0.05mg/1 KIN +0.1 mg/l GA, After three weeks, meristems were transferred to MS media supplemented with BA, KIN, IBA, NAA and IAA singly or in combination for shoot elongation and root initiation. Among the different treatments, MS + 1.0 mg/1 BA + 0.1 mg IBA + 0.3 mg/1 GA, showed good responses for shoot initiation with elongation. On the other hand good rooting was observed when 0.5 mg IBA and 0.1mg/ NAA were used in MS semisolid medium. Ten works old in vitro plantlets were successfully planted in soll through gradual acclimatization.&#13;
Immature embryos were excised from seeds of two genotypes (GBBG 6 and GBBG 14) of bitter gourd and cultured in invariably underwent callasing followed by multiple shoot formation, but in some cases single shoot was observed MS medium supplemented with 1 μM BAP + 0.01 M1 NAA was found to be suitable for adventitious multiple shoots and root regeneration. Addition of 40-100 mg/l casein hydrolysate (CH) improved shoot and root regeneration efficiency. For single shoot and root formation, MS medium with 0.3521 M1 GA+ 100 ml CH was very effective Aspangine and L-glutamine had no role in to tissue differentiation of immature embryo culture.&#13;
High frequency of direct organogenesis from immature leaflet explants has been achieved in biter gourd. Here shoot buds were found to develop from leaflet on MS medium containing 3.0mg/l BAP and 0.5mgl IAA within 7-8 weeks. Proliferation of regenerated shoot buds, formation of shoots and their elongation took place in the same medium. Regenerated shoots formed healthy roots when they were further grown on MS median supplemented with 0.5mg IBA.&#13;
Mutiple shoots from the immature cotyledenory nodes of two genotypes of bitter gourd were induced in MS media with GA, IAA, IBA, NAA, KIN and BAP. The shoots continued to increase in number for 5-6 weeks. On the medium, BAP 2 mg in combination with 0.1 mgl IAA + 2 mg/l GA, was the most effective medium for adventitious shoot proliferation from immature cotyledonary node. BGGB1 and BOGB14 genotypes produced over 84% and 80% shoots, respectively on this medium in 6 from the time at inoculation of primary explants. BOGBI was found to be better in rape than B00814 in most of the treatments.&#13;
Somatic embryogenesis and organogenesis with subsequent plantlets regeneration were achieved in callus cultures derived from immature cotyledon of bitter gourd using MS semisolid besal medium supplemented with different concentrations and combinations of cytokinin (BAP and KIN) and on (IAA and IBA). Among the different combinations, the media supplied with BAP and IAA were more effective in the induction and proliferation of callus then KIN+ IBA or KIN+ IAA or BAP+ IBA. The highest numbers of somatic embryos were obtained in media fortified with IAA (1.0 mg/l) and BAP (1.0 mg). BAP (2.5 mg) in combination with 0.2 mg/l IAA was found table for shoot organogenesis.&#13;
Rapid and reproducible transformation system for bitter gourd using Agro bacterium fciens mediated gene delivery was developed. Inmature cotyledonary node and immature cotyledon from green immature fruits that have been allowed to imbibe were used as explant, and regeneration we achieved vie organogenesis and embryogenesis, respectively, Cotyledonary node and cotyledon were co-cultured in MS media with 2.0 mgl BAP +0.1 mg IAA +2.0 mg/l GA and 2.5 mg BAP 0.2 mgl IAA, respectively. Histochemical GUS assay of the explants, exsand shoots (newly formed) released that they were GUS positive. Of the explants so the studied cotyledon was found to be more susceptible to Agrobactreium (LBA4404, pB1121) and infection moreover, successful regeneration was also observed. It was the first step to produce transgenic bitter gourd using this gene delivery method and it will also provide a basis for further research to generate transgenic bitter gourd plants.

<title>Fish and Fishery of Aspidoparia (Cypriniformes: Cyprinidae) of the River Padma</title>

<description>Fish and Fishery of Aspidoparia (Cypriniformes: Cyprinidae) of the River Padma
Sultana, Nasrin
Bangladesh has vast fishery resources. The inland water areas of the country comprises 1.03 million hectares of rivers, canals and estuaries; 1,14,161 hectares of natural depressions such as the beals' and 'haors'; 1,61,943 hectares of ponds and tanks, 5,488 hectares of ox-bows; 68,800 hectares of Karnafuli reservior; 2.8 million hectares of flood plains and 87,300 hectares of brackish water aquaforms (Rahman, 1989).&#13;
A total of 260 species of indigenous species of fin fishes are found in the freshwater habitats of Bangladesh and majority of these fishes are small sized (Rahman, 1989).&#13;
The small indigenous fishes (SIS) form an important human food item, rich source of complete proteins containing all the essential aminoacids in right proportion. Fish protein is said to be more healthier and cholesterol free and also contains fatty acid which help in cholesterol absorption in the body tissues. The people are advised to take much smaller fish than meat. According to FAO report, (1991), fish contain 72% water, 19% protein, 89% fat, 0.15% calcium 0.25% phosphorus and 0.10% vitamin A,B,C and D. National Household Expenditure Survey (NHES) shows that anmel fish consumption in Bangladesh peaked in 1985 at 13.2 kg/person, had declined to 12.6 kg/person by 1992. This is in the same agreement with the information developed by North West Area Development Study (NWADS), which shows that overall fish supply has stagnated, resulting in price increase in real terms of over 2.8% per annum in the Northwest Region (Interim Report Vol-5 ADB February, 1997).&#13;
The SIS fishes thus, make a very significant contribution to the daily intake of fish. Moreover, Siddiqui (1985) reported that in Bangladesh about 80 percent of&#13;
the population is poor and they mainly depend on small size fish for their daily supply of animal protein at a reasonable price. Another advantages of small size fish is that they could easily breed and grow in water bodies, where culture of other major fishes are impossible. However, the ever expanding programme of flood control, drainage and irrigation is interfering with the whole ecological system in fishery resources, thereby causing both loss and degradation of their habitats. Which will inevitably lead to diminution and even disappearance of 95 percent of inland fish production.&#13;
The present species 4. morer is mostly available in the river systems of Bangladesh. The biology of this species had been reported by Sultana (1991), Bhuiyan et al. (1992) compared the past and present data on the landing of the species together with the market price found that the natural production of the species is decreasing due to construction of the Farakka Barrage and oder FCD projects which caused detremental effect on the national aquatic system. Moreover, over exploitation of fish population and indiscriminate use of agrochemicals also adversely affected the fisheries resources.&#13;
A. morar is an important species due to its high nutritional value in terms of protein content. Inspite of its usefulness as a source of protein, no detailed studies on the chemical and biochemical investigation has so far been reported.&#13;
This is a small sized fish with a maximum size of 145 man, feiches the hightest market price due to its taste and flavour. This fish generally live in shallow water of the sandy bottom and medium current areas of the rivers. We hope the present finding may help to increase its population in the river Padma near Rajshahi
