Item Abdomino-scrotal hydrocele (a case report).(1988-07-01) Gupta, S K; Shukla, V K; Roy, S KItem Adverse reaction following immunisation--a review.(1990-10-01) Roy, S KItem The binding of progesterone in different parts of the rabbit uterus during implantation.(1980-12) Puri, Raj K; Roy, S KProgesterone receptors, both nuclear and cytosolic, were determined in the embryonic and inter-embryonic segments of the rabbit uterus at 6, 7 and 8 day post-coitum. At day 6 postcoitum a higher concentration of nuclear receptor in the embryonic segment was observed compared with that in the inter-embryonic segment. A reverse situation was observed in the case of cytoplasmic receptors. On the 7th day post-coitum, no significant alteration in the concentration of either kind of the receptors was observed. However, on day 8, a higher concentration of both nuclear and cytosolic receptors at the embryonic site was observed compared to that in inter-embryonic segment. Since receptors are influenced only in the immediate vicinity of the blastocyst, it can be suggested that the blastocyst plays a role in the induction of its own implantation. Further, at day 8 increase in receptor concentration at the embryonic site may be related to the presence of decidual tissue at this site.Item Biological profile of 1, 2-diethyl-1, 3-bis-(p-methoxyphenyl-1-propene-A new oral non-steroidal contraceptive.(1980-06-01) Prakash, A O; Ghosh, M; Tewari, S C; Rastogi, S N; Roy, S KItem Biological profile of Centchroman--a new post-coital contraceptive.(1977-12-01) Kamboj, V P; Setty, B S; Chandra, H; Roy, S K; Kar, A BItem Burkitt's lymphoma.

The receptor levels when compared among its various anatomical segments, were the same in ampulla, isthums and uterus but maximum in ampullary-isthmic junction. Significant differences were observed in mated animals at 14, 24, 34, 48, 70 and 144 h after coitus. The receptor concentrations in portions of the fallopian tube showed no significant change between 14 and 24 h after coitus, except for a decrease in ampullary-isthmic junction at 24 h. At 34 h the concentration of receptor further decreased in all parts of the tube. At 48 and 70 h after coitus, receptor concentrations decreased gradually in ampulla and ampullary-isthmic junction, while isthmus showed a gradual increase. At 144 h, the receptor concentration showed no further change in ampulla and ampullary-isthmic junction; however, isthmus showed a decline. The uterine receptor concentration declined steadily from estrus till 70 h after coitus, however, it was increased at 144 h. The dissociation constant (Kd) of cytosol receptor in all the tissues at estrus and during early pregnancy was found similar. The implications of these changes in relation to the normal ovum transport have been correlated in this paper.Item Determinants of Undernutrition in Children Under 2 years of Age From Rural Bangladesh.(2012-10) Ahmed, A M Shamsir; Ahmed, Tahmeed; Roy, S K; Alam, Nurul; Hossain, Md IqbalThis study aimed to assess the determinants of under nutrition among under-two year old children of rural Bangladesh. The data of the National Nutrition Program baseline survey conducted in 2004 was analyzed, which included 8,885 under-two children and their mothers. Among the children studied, 41%, 35% and 18% were stunted, underweight, and wasted; and 16%, 11.5% and 3% were severely-stunted, -underweight, and –wasted, respectively. Multivariate analysis revealed that undernourished children were less likely to be female and having received measles vaccination, more likely to have suffered from diarrhea in the previous two weeks, and more likely to have older- (>30 years), shorter- (<145 cm), undernourished- (BMI ≤18.5 kg/m2) and illiterate/less educated mother. Children with moderate stunting and underweight were more likely to reside in households with un-hygienic toilet. Children with all forms of under nutrition were more often from families with lowest quintile of asset index. The identified associated/risk factors can be used for designing and targeting preventive programs for undernutrition.Item Effect of 3-(3,4-dihydro-6-methoxy-2-naphthyl)2,2-dimethyl pentanoic acid--an antifertility agent--on in vitro uptake of estradiol 17beta-6, 7(3)-H in rat uterus.(1976-09-01) Ghosh, M; Roy, S K; Gopalchari, RItem Effect of a contraceptive suture on incorporation of dl-valine-1-14C in the uterine fluid protein of rats.(1968-10-01) Kar, A B; Roy, S K; Singh, V PItem Effect of Centchroman (67/20) and 78/224 on nucleic acid and protein biosynthesis during implantation in rats.(1985-12) Srivastava, A D; Ratna, Sanjeev; Roy, S KThe biosynthesis of nucleic acids and proteins was studied in rat uterus by following the incorporation of [3H]-thymidine, [3H]-uridineand[14C]-leucinein control and pregnant rats in the presence and absence of two anti-implantation drugs. One of the drugs, 78/224 caused a significant increase in incorporation whereas the other drug, Centchroman, caused an inhibition in incorporation of all the three precursors. The implications of these changes in the light of estrogenicity, agonist and antagonist actions of anti-estrogens have been analysed. The importance of homeostatic mechanisms involved in nucleic acids and proteins for the maintenance of constant internal milieu for blastocyst attachment has been discussed.Item Effect of Centchroman on plasma estrogen & progesterone levels in rat.(1977-12-01) Ghosh, M; Roy, S KItem Effect of contraceptive suture on biochemical composition of uterine fluid of protein deficient rats.(1972-11-01) Singh, V P; Roy, S K; Kar, A BItem Effect of copper and nylon-IUD on uterine carbonic anhydrase activity.(1985-06-01) Ghosh, M; Chowdhury, A R; Roy, S KItem Effect of copper intrauterine contraceptive device on the estrogen & progesterone uptake in ovariectomized rat uterus.(1977-06-01) Ghosh, M; Roy, S K
