In the present study, the prevalence of intestinal parasitic infestation was investigated among the outdoor patients including teacher, student and staff of the Dhaka University treated at Dhaka University Medical Centre. A total of 380 stool samples were examined. Four species of intestinal parasites were identified, two protozoans (Entamoeba histolytica and Giardia intestinalis) and two nematodes (Ascaris lumbricoides and Trichuris trichiura). The prevalence of parasitic infestation was 24.73%. The prevalence of E. histolytica was 3.95%, G. intestinalis 6.31%, A. lumbricoides 11.84% and T. trichiura 2.63%. The prevalence was higher in case of staff (32.31%) and lower in case of teacher (13.16%). Highest prevalence observed during the rainy season (29.3%) and lowest in winter (19.4%). Female patient showed higher prevalence (31.25%) compared to male (24.14%). The rate of infection was higher (28.3%) among the patients, who used to drink unboiled water. The present study revealed that parasitic infection among the outdoor patients of Dhaka University Medical Centre is alarmingly high.

Total Volatile Base Nitrgen (TVB-N) and Trimethylamine Nitrogen (TMA-N) of Galda ( Macrobrachium rosenbergii ) and Bagda ( Penaeus monodon ) at ambient temperature was compared at Fish Quality Control Laboratory of Fisheries and Marine Resource Technology Discipline, Khulna University, Bangladesh. The TVB-N and TMA-N were determined by using Conway's Micro-diffusion Technique. The nature of biochemical changes was studied up to complete spoilage. The TVB-N contents of Galda and Bagda ranged between 6.65±0.12 mg- N/100g to 8475±0.22 mg-N/100g and 6.72±0.18 mg-N/100g to 91.43±0.49 mg-N/100g. The TMA-N contents of Galda and Bagda ranged between 6.64±0.12 mg-N/100g to 39.38±0.33 mg-N/100g and 6.81±0.17 mg-N/100g to 71.41±0.35 mg-N/100g. A slight higher amount of TVB-N was observed at all stages in Galda as compared to Bagda. TMA-N contents significantly varied between Galda and Bagda (P≤0.05). At all stages of spoilage Bagda showed higher amount of TMA-N. Keywords: Post mortem; TVB-N; TMA-N; Galda and Bagda. DOI: 10.3329/ujzru.v28i0.5278 Univ. j. zool. Rajshahi. Univ.

The study was aimed at standardization of cryopreservation protocol for the common carp, ( Cyprinus carpio ) spermatozoa for using in the artificial propagation. Three extenders (Alsever’s solution, egg-yolk citrate and 0.9% NaCl) were combined with three cryoprotectants (ethanol, methanol and DMSO). Two-step freezing protocol (5°C to -4°C at a rate of 4°C per minute then -4°C to -80°C at a rate of 10°C per minute and finally held for 10 min) was carried out in a computer-controlled freezer where 0.25 ml straws containing spermatozoa were stored in a liquid nitrogen container at -196°C. Alsever’s solution with ethanol, Alsever’s solution with methanol and egg yolk citrate with DMSO gave better motility (%) in both pre-freeze (93.33±1.05, 90±1.83 and 88.33±2.11, respectively) and post-thaw (80±4.28, 74.17±3.96 and 76.67±4.59, respectively) periods whereas, 10% cryoprotectant gave the best motility during post-thaw period. Considering both pre-freeze and post-thaw motilities of the common carp spermatozoa, 1:9 was the best ratio for the milt and cryodiluents. The egg yolk citrate with DMSO yielded the best fertilization (37.67±1.76%) and hatching (28.67±1.85%) compared to other combinations under study.

The study was conducted to determine a suitable feed for the desirable growth of riverine catfish Rita rita (Hamilton) from January 2006 to December 2006. The experiment had three treatments with three replicates. Nine chambers of the raceway each of size 1.83 × 1.12 sq meter were used. Local prawn, chicken viscera and commercially available formulated feed (CP) were supplied in treatment T 1 , T 2 and T 3 , respectively at the rate of 7% body weight. Feed was supplied twice in a day in the early morning and in the evening as the fish is nocturnal. The initial average weight of fish was 24.93±0.05g, 24.99±0.04g and 24.95±0.04g in T 1 , T 2 and T 3 , respectively. The final weight of the fish under three treatments was 425.05±1.04g, 425.68±1.05g and 177.61±1.45g respectively. The initial length was 8.48±0.02, 8.49±0.02 and 8.50±0.01 in T 1 , T 2 and T 3 , respectively. The final length was 25.22±0.06 cm, 25.21±0.14 cm and 14.87±0.13 cm in T 1 , T 2 and T 3 , respectively. The mean final weight and length was significantly (p 0.05) between T 1 and T 2 in terms of final weight and length was concerned. Better growth performances, however, were observed in T 2 and T 1 , where prawn and chicken viscera were supplied as feed respectively. Lowest growth performance was observed in T 3 where formulated feed (CP feed) was supplied. Key Words: Riverine Catfish; Feed; Growth; SGR; Survival. DOI: 10.3329/ujzru.v28i0.5279 Univ. j. zool.

Repellents, fumigants, feeding deterrents, growth inhibitors and insecticides of natural origin are rational alternatives to synthetic insecticides. Some plants draw a special attention for their low lethal and other environment-friendly activities (Talukder & Howse, 1995). Epiphytes or air plants that do not normally root in the soil but grow upon another living plant, draw attention as a source of bioactive potentials. Use of these plants in the traditional system of folk medicine is well known (Mallavadhani et al., 2003). Epiphytes of Bangladesh remain untouched from investigation for their bioactive potentials. In this proposition six epiphytic plants viz. Dendrophthoe falcate (L.f.) Ettingsh. Cuscuta reflexa Roxb., Drynaria roxburghii (Bory) J. Sm., Ficus lacor Buch.-Ham., Vanda roxburghii R. Br. and Loranthus longiflorus Desr., were taken into consideration for evaluating their repellent activities.

The turmeric, Curcuma longa L. is a common spice belongs to the family Zingiberaceae. It is useful in disease of blood, leucoderma, scabbies, urinary discharges, inflammations, snake-bite, small pox, swelling, etc. (Kirtikar & Basu, 1935); in chronic otorhoea (Nadkarni, 1998); in antibacterial infection (Rambir Singh et al., 2002). It contains ar-turmeron, ar-curcumene, α and β pineane sabinene, myrcene, α-terpinene, P-cymenene, perillyl-alcohol, turmerone, eugenol, iso-eugenol, etc. (Hussain et al., 1992). However, C. longa has some phytochemical and medicinal properties, but its use for the control of crop pests and the information on its efficacy against stored grain pest is still scanty. So, the insecticidal and repellent activity tests of C. longa extracts have been attempted and the investigation has been designed to evaluate the efficacy of the test plant as a possible source of potential secondary metabolites to be used as environment friendly pest control agents.
姜黄，姜黄是姜科的一种常见香料。可用于血病、白皮病、疥疮、尿液、炎症、蛇咬伤、小痘、肿胀等(Kirtikar & Basu, 1935);慢性耳炎(Nadkarni, 1998);(Rambir Singh et al.， 2002)。它含有-姜黄酮、-姜黄烯、α和β蒎烯、沙宾烯、月桂烯、α-萜烯、对丁香烯、紫苏醇、姜黄酮、丁香酚、异丁香酚等(Hussain et al.， 1992)。然而，龙葵具有一定的植物化学和药用特性，但其在防治作物病虫害方面的应用和对储粮病虫害的防治作用还很少。因此，本研究试图对龙骨草提取物进行杀虫驱避活性试验，并对其作为潜在次生代谢物来源作为环境友好型害虫防治剂的功效进行评价。

The present experiment was carried out to determine the effects of methionine and tryptophan on some quantitative traits of silkworm, Bombyx mori L. Mulberry leaves were treated with 250,500,750 and 1000 ppm of amino acids and were provided to the worms as food. Compared to the controls amino acids (especially 500 and 750 ppm) significantly increased the fecundity, fertility, adult emergence, developmental periods and longevity of B. mori adults but decreased the mortality. Key words: Amino acids; Bombyx mori; fecundity; mortality; longevity. DOI: 10.3329/ujzru.v28i0.5280 Univ. j. zool. Rajshahi Univ. Vol. 28, 2010 pp. 15-19
本试验研究了蛋氨酸和色氨酸对家蚕某些数量性状的影响。将桑叶分别以250、500、750和1000 ppm的氨基酸处理，作为家蚕的食物。与对照相比，氨基酸(特别是500和750ppm)显著提高了家蚕成虫的繁殖力、育力、羽化、发育期和寿命，但降低了死亡率。关键词:氨基酸;家蚕;多产的;死亡率;长寿。DOI: 10.3329/ujzru.v28i0.5280 Univ. j. zool。拉杰沙希大学，2010年第28卷，第15-19页
