  Comparative efficacy of neem and karela with insulin and glibenclamide was studied on some lipid profile(total cholesterol, triglyceride, HDL cholesterol and LDL cholesterol) in 40 rabbits from February to April, 2003. Rabbits were randomly divided into 8 equal groups and rabbits of group A and B were kept as non hyperglycemic control and hyperglycemic control respectively. Hyperglycemia was induced in 7 groups of rabbits (B, C, D, E, F, G and H) by administering alloxan at a dose of 200 mg/ kg body wt. s/c. After 15 days of alloxan injection, 6 groups of rabbits (C, D, E, F, G and H) were treated with insulin, glibenclamide, neem seed kernel powder (NP), neem seed oil (NSO), neem leaf extract (NLE) and karela fruit juice (KFJ) at the dose rate of 5 U/kg, 0.5 mg/ kg., 500 mg/kg , 1 ml/kg , 500 mg/ kg and 100 mg/kg body weight respectively for consecutive 28 days. All the control and treated rabbits were closely observed during pre-treatment, 28 days of treatment and also for 14 days of post-treatment period and the lipid profile was investigated. Due to alloxan induced diabetes the content of total cholesterol increased significantly (P<0.01) in all groups except the normal control group A. On 28th day of treatment period the amount of total cholesterol, serum triglyceride, HDL cholesterol and LDL cholesterol were significantly(P<0.01) reduced to extent of 15-30%, 15-46%, 15-25% and 16-32% respectively that were close to the initial value before the commencement of dosing(day 0) except with KFJ which had very little effect(15%). Glibenclamide reduced the triglyceride level to a greater extent (46%) than other drugs. Insulin and glibenclamide showed similar efficacy (25%) in reduction of the serum HDL cholesterol level and (31-32%) in LDL cholesterol level. It was observed that patent drugs insulin and glibenclamide induced better and almost equal efficacy in reducing the parameters whereas herbal preparations of neem, i.e., NP, NSO and NLE showed almost equal but less efficacy than two patent drugs and Karela fruit juice was found to be least effective. It may be concluded that instead of less efficacy than patent drugs, the efficacy of neem and karela was also encouraging.

  Comparative efficacy of neem and karela with insulin and glibenclamide was studied on some biochemical parameters (Blood glucose, Serum urea and Serum creatinine) in 40 rabbits from February to April, 2003. Rabbits were randomly divided into 8 equal groups and rabbits of group A and B were kept as non hyperglycemic control and hyperglycemic control respectively. Hyperglycemia was induced in 7 groups of rabbits (B, C, D, E, F, G and H) by administering alloxan at a dose of 200 mg/ kg body wt. s/c. After 15 days of alloxan injection, 6 groups of rabbits (C, D, E, F, G and H) were treated with insulin, glibenclamide, neem seed kernel powder (NP), neem seed oil (NSO), neem leaf extract (NLE) and karela fruit juice (KFJ) at the dose rate of 5 U/kg, 0.5 mg/ kg., 500 mg/kg , 1 ml/kg , 500 mg/ kg.and 100 mg/kg body weight respectively for consecutive 28 days. All the control and treated rabbits were closely observed during 28 days of treatment and also for 14 days of post-treatment period and biochemical parameters were investigated. Blood glucose levels were significantly (P<0.01) reduced in all treated six groups of rabbit to the extent of 25-42% in comparison to their pre-treatment values. Similarly, serum urea and creatinine values were reduced significantly (P<0.01) to the extent of 15-25% and 4-15% respectively on 28th day of treatment in comparison to their 21th day treatment values. It was also observed that patent drugs insulin and glibenclamide induced better and almost equal efficacy in reducing the parameters whereas herbal preparations of neem, i.e., NP, NSO and NLE showed almost equal but less efficacy than two patent drugs and Karela fruit juice was found to be least effective. It may be concluded that instead of less efficacy than patent drugs, the efficacy of neem and karela was also encouraging.

  Ectoparasites are distributed all over the world but occur mainly in tropical and sub-tropical countries. Ectoparasites result in a considerable amount of blood loss, disturbances in feeding, retarded growth and decreased production. Among the ectoparasiticides ivermectin is a new endectocide and diazinon is another commonly used ectoparasiticide available in Bangladesh. The present research was designed to study the comparative efficacy of ivermectin and diazinon against ectoparasites, their effects on some clinical, hematological and biochemical parameters in sheep. For this purpose 25 sheep heavily infested with ticks and lice were randomly divided into 5 equal groups, i.e. groups B, C, D, E and F. Another group of 5 sheep free from parasitic infestation were also selected and kept as uninfected control (group A) and group B was kept as infected control group. The sheep of groups C and D were treated with recommended (200 g/kg b.w.) and higher than recommended (300 g/kg b.w.) doses of ivermectin subcutaneously. The sheep of groups E and F were treated with diazinon (spray) at recommended (0.1% soln.) and higher than recommended (0.2% soln.) doses. After injection of ivermectin and spray of diazinon all four treated and two groups were kept for 28 days and clinical, hematological and biochemical parameters were investigated at 7 days intervals. The data were collected and analyzed statistically between control and treated groups by using student ‘t` test . On the basis of lice and tick count, the efficacy of ivermectin was found 100% whereas diazinon was 82-85% effective against ectoparasitic infestation in sheep. Ivermectin and diazinon increased the feeding efficiency as compared to infected control groups. No adverse effects was observed following both the dose of ivermectin and recommended dose of diazinon. In this study, the hematological parameters, i.e. TEC and Hb% were increased significantly (p<0.01) in all treated four groups to the extent of 35-70% and 10-21% respectively. On the other hand, ESR values were decreased significantly (p<0.05). No significant change was observed on SGOT and SGPT following both the doses of ivermectin injection. However, SGOT and SGPT values were significantly (p<0.01) increased to the extent of 46-90% and 25-46% within 7-14 days of diazinon spray. However, elevated values of SGOT and SGPT became almost normal within 28 day of treatment. Among the recommended and higher than recommended doses of ivermectin and diazinon, the recommended dose of both the drugs is suitable for therapeutic purpose. Among the two drugs, ivermectin was found to be the best drug against ectoparasites showing prompt and 100% efficacy.

  Effect of different eyes number viz., E1, E2 and E3 per cut seed tuber and five levels of nitrogen viz., N0, N60, N120, N180 and N240 and their all possible combinations on the growth, yield and tuber size grading of potato (cv. Diamant) was studied at the Bangladesh Agricultural University during 1997 and 1998 cropping season. Canopy coverage, main stem number hill-1, tuber number hill-1 significantly increased with the increasing number of eyes in cut seed tuber piece. Cut seed tuber piece with 3 eyes required the shortest period to shoot emergence, but produced the smallest tubers. Three eyed cut seed tuber produced the maximum tuber yield, 31.7 t ha-1, which was statistically similar to 2-eyed seed piece (31.4 t ha-1). Higher nitrogen significantly increased all the parameters studied and took less number of days to shoot emergence and tuber maturity. 240 KgN ha-1 produced the maximum tuber yield (35.2 t ha-1), but the performance of N180 and N240 showed non-significant variation. Grade A (>55 mm) and B (55-40 mm) sized tubers increased, but grade C (40-28 mm) and D (<28 mm) sized tubers decreased with the increase of nitrogen. The highest tuber yield was obtained from the combination (s) of E2 X N240 or E3 X N180. Maximum tubers of grade A, B, C and D were produced from the combinations of E1/E2 X N240, E1 X N60/N240 or E2 X N60/N180 or E3 X N60, E3 X N0 and E2 X N0, respectively. From the economic point of view, 2-eyed seed tuber piece and 180 KgN ha-1 were the best either singly or combinely to achieve maximum growth and yield potential.
