Acidosis conditions either acute or chronic following ingestion of excessive amounts of readily fermented carbohydrate are great production problems for goat in Bangladesh. This study designed to investigate the prevalence of lactic acidosis and then response to different therapeutic agents. For this purpose, 1,128 goat were examined at outdoor District Veterinary Hospital, Faridpur, Bangladseh for treatment of which 40 goats were found positive for lactic acidosis showing 3.55% prevalence of disease. The highest occurrence found in female (4.64%) of over 3 years age (4.64%) in indigenous goat (2.7%). For therapeutic assessment the forty affected goats were divided into four groups A, B, C and D comprising of 10 animals each. Group A were given magnesium hydroxide 8% w/v at 1 g/kg body weight orally. In group B magnesium hydroxide 8% w/v at a dose as group A combination with 7.5% sodium bicarbonate at the rate of 0.9 ml/Kg body weight intravenously administered. Goat in group D were treated with mixture of ginger, nuxvomica, sodium carbonate, cobalt sulphate, dried ferrous sulphate and thiamin mononitrate at the rate of 1 g/kg body weight orally. Goat of group C treated with combination drugs of group A, B and D. The rectal temperature, pulse rate, respiration rate, was performed before and after treatment. It was found that the highest recovery in group C with an average period of $21{\pm}1.8$ hours. It was concluded that lactic acidosis is a common disease of goats and its severity can be effectively reduced by using combination drugs.

Mass mortality of Halocynthia roretzi has been occurred in culturing grounds of southern coast of Korea during the long period of summer drought and the unusal high water temperature in 1988. Especially Halocynthia roretzi was damaged severely in 2 years group. Therefore we verified these phenomena by observing the environmental factors of culturing grounds and by evaluating oxygen consumption rate in indoor experiment. In culturing grounds, the mortality rate was high in Namhae Mizo area where water temperature was the highest and the lowest in dissolved oxygen concentration as low as 3.76m/l in field observation. In indoor experiment, the higher the water temperature, the more mortality was occurred and the salinity above 30 had no effect on its mortality. In oxygen consumption rate experiment, the smaller needs more oxygen than larger one, i. e., oxygen demand per unit weight was higher in 2 years group than that of 3 years. The theoretical and the actual minimum oxygen demands(MOB) for preventing asphixation was 3.7ml/kg/h at $20^{\circ}C$ and 6.3ml/kg/h gat $25^{\circ}C$, But actual MOD was 4.3ml/kg/h at $25^{\circ}C$ in indoor experiment. It seemed that mass mortality of Halocynthia roretzi in summer was caused by metabolism disorder due to insufficient oxygen level influenced by the high water temperature and the high density of Halocynthia roretzi, which results in the paucity of oxygen especially in 2 years groups.

Shade-dried flowers of Sarcostemma brevistigma Wight Syn (SBF) belonging to Asclepiadaceae yielded a rare flavonol glycoside viz., Quercetin 5a prenyl, 3-O-glucosyl, 7-O-(4c-p-coumaroyl) neohesperidoside which were characterized based on chemical and spectral (including 2D NMR) studies. The ethyl acetate fraction of alcoholic concentrate (test sample) of flowers of this plant (SBF) was evaluated for its hepatoprotective and inhibition of lipid peroxidation activities to investigate the scientific basis of the traditional uses. The oral administration in varying doses viz., 125 and 250 mg/kg of aqueous suspension of SBF to rats for 7 days produced significant (P < 0.01) hepatoprotective effect comparable to that of standard drug silymarin. The SBF afforded good hepatoprotection against $CCl_4$ induced elevation levels of serum marker enzymes, serum bilirubin and liver weight. The free radical scavenging effects of SBF and flavonol glycoside (SA) were assigned by $Fe^{2+}$/ascorbate induction method (in vitro), which revealed the inhibition of lipid peroxidation. The SBF and SA showed prominent anti-lipid peroxidation activity ($IC_{50}$ about $\sim$180 mg/ml and 11.0 mg/ml respectively), which was comparable to standard drug curcumin ($IC_{50}$ about $\sim$8.25 mg/ml). Thus the hepatoprotective activity of SB could be correlated to the free radical scavenging property of the flavonol glycoside.

Quantitative determination of capsaicin in biological fluid was investigated. The pharmacokinetic study of capsaicin in rabbits was performed by high-pressure liquid chromatography, equipped with a microparticulate reversed-phase column and a fixed wavelength detector. Elution was carried out using methanolwater(70:30). It allows the quantitative determination at 8-400 ng level. When single dose of capsaicin(4mg/kg) was given to rabbits intravenously, the elimination phase was extremely short with average half-life to 17.35 minute. Urine excretion of capsaicin itself during first 2 hours after intravenous administration (4mg/kg) was 0.004-0.04% of the administered amount. The maximum plasma concentration of capsaicin after oral administration (300mg/kg) was $4{\times}10^{-7}$g/ml at 40 minutes. The $LD_{50}$ of capsaicin in mouse was 0.40mg/kg (i.v.) and 47.2 mg/kg (p.o.) which was determined by Litchfield and Wilcoxon's method, suggesting that the gastrointestinal absorption of capsaicin is poor.

Growth performance, nutrient digestibility and changes in caecal fermentation pattern was studied on four groups of 8 grower rabbits (soviet chinchilla) each, fed on diets containing 17 to 18% CP and $10.4-11.00MJ\;DE\;kg^{-1}$ feed. The complete diets contained mulberry leaves along with other feed ingredients at 0 (LH), 15 (ML15), 30 (ML30) and 45% (ML45) levels. In LH diet ground lucerne hay was added at 15% of the diet as roughage source. The diets were uniform in other nutritional parameters except the higher amount of hemicellulose (18.7 and 16.5%) in LH and ML15 diets. The performance of grower rabbits was better (p<0.05) on LH and ML15 diets in terms of twelve weeks weight (kg), total gain (g), average daily gain (ADG) and feed efficiency (%). Different levels of mulberry leaves in the diet did not influence the dry matter intake. Digestibility of nutrients for DM, OM, CP, NDF and energy was uniform in all the diets but the digestibility of CF, ADF and cellulose was higher (p<0.01) on ML15, ML30 and ML 45 diets. The hemicellulose digestibility was significantly higher (p<0.01) on LH (44.52%) and ML15 (48.00%) compared to ML30 (33.54%) and ML 45 (39.17%) diets. The nitrogen retention (% of intake) was higher (p<0.05) in LH and ML15 diets than ML30 and ML45 diets. The caecum weight as percent of intestine weight consistently increased (p<0.05) with increasing content of mulberry leaves in diets. Total nitrogen and $NH_3$-N was higher on LH and ML15 diets. It is concluded that incorporation of mulberry leaves can replace Lucerne hay in complete rabbit feed (15% in diet). Even at higher level i.e. 30 and 45% of the diet mulberry leaves based complete feed gave promising results.

A lab-scale ensiling study was carried out to investigate the fermentation quality of water hyacinth (WH) supplemented with molasses, rice bran, as an absorbent, and an inoculant in the form of fermented vegetable juice and their combinations. After wilting the water hyacinths for 7 h to a dry matter (DM) content of 240 to 250 g/kg, the following treatments were applied: i) Control (C), WH only; ii) WH with sugarcane molasses at 40 g/kg WH (CM); iii) WH inoculated with fermented vegetable juice at 10 ml/kg WH (CI); iv) CM and CI (CMI) combined; v) WH with 150 g rice bran/kg WH (CA); vi) CA and CI combined (CAI); vii) CA and CM combined (CAM); and viii) CA, CM and CI combined (CAMI). After application of additives, the differently treated forages were mixed and ensiled in triplicates in 1,500-ml polyethylene jars. After ensiling for 3 d, pH values in all treatments, except C and CI, had decreased to approximately 4.0 and remained low till 14 d. After 56 d, pH had increased between 0.4 to 0.9 pH-units compared to those at 14 d. The ammonia nitrogen ($NH_3$-N) concentration ranged from an acceptable level in treatment CM (8 g/kg N) to a high $NH_3$-N value in treatment CMI (16 g/kg N). Lactic acid formation was higher in CI than in all other treatments. Butyric acid contents, which indicate badly fermented silages, were low in all silages (<2 g/kg DM). There were two-way interactions (p-values from <0.001 to 0.045) for almost all fermentation end-products and pH, except for the molasses${\times}$inoculant interaction on $NH_3$-N (p = 0.26). Significant 3-way interactions were found on all observed variables except for weight losses of silages. It is concluded that conserving wilted WH as silage for ruminants may be improved by the addition of molasses or rice bran.

This study was undertaken to evaluate the antitumor activities of Cordyceps militaris of silkworm pupa (CMP) and silkworm larva (CML), as compared with the effect of cordycepin, an active compound found in Cordyceps militaris. Antiproliferation effect of the test materials were evaluated in the sarcoma-180 cells using the MTT test. For the in vivo study, ICR mice were inoculated i.p. with 1.0 ${\times}$ 10$^{6}$ sarcoma-180 cells/mouse on Day 0, and were again i.p. injected with one of the following substances from Day 1 to Day 10 : saline (control group), 50 mg/kg (CMP50, CML50) ,100 ma/kg (CMP100, CML100), or 200 mg/kg (CMP200, CML200) of Cordyceps militaris water extracts, or 1 mg/kg (C1), 2 mg/kg (C2), or 4 mg/kg (C4) of cordycepin. Pretreatment of the sarcoma-180 cells with 100 mg/ml, 500 mg/ml, and 1000 mg/ml of CML (60.1$\pm$2.5％, 49.8$\pm$3.7％, and 45.4$\pm$0.1％ of the value for untreated control cells, respectively) or CMP (68.3$\pm$2.1％, 55.1$\pm$0.9％, and 51.4$\pm$3.5％ of the value for control cells, respectively) for 48 hrs significantly decreased the survival rate (proliferation) of tumor cells (p<0.05). Body weight of the control mice bearing ascites tumor and injected with saline was 1.4 times of the value for normal animals at day 18. Mice bearing ascites tumor and injected with cordycepin (1, 2, or 4 mg/kg) exhibited a significantly lighter body weight compared with the control mice, while animals injected with CMP or CML (50, 100, or 200 mg/kg) showed a significantly lighter body weight compared with the mice injected with cordycepin. Mice injected with CMP50, CMP100, or CMP200 mg/kg (or CML50, CML100, or CML200 mg/kg) showed a 133％ (or 90％), 80％ (or 62％), and 68％ (or 52％) longer mean survival time, and those treated with C1, C2, or C4 exhibited a 54％, 91％ and 80％ longer survival time compared to the value for control mice injected with saline. These results indicate that the hot-water extracts of Cordyceps militaris of both silkworm pupa and silkworm larva have an anti-proliferation effect of tumor cells as well as the life prolongation effect in mice bearing ascites tumor, which are superior to the activities of cordycepin.

An analytical method for the simultaneous determination of four tetracycline (oxytetracycline, tetracycline, chlortetracycline, doxycycline) in egg samples was developed and validated using liquid chromatography with ultraviolet detection. Egg samples were extracted by the liquid-liquid extraction based on acetonitrile. The chromatographic separation was achieved on a reverse phase C8 column with gradient elution using a mobile phase of 20 mM oxalic acid (pH 1.5)/acetonitrile. The procedure was validated according to the Food Drugs Administration guideline determining accuracy, precision, and limit of detection. Mean recovery of tetracyclines from spiked egg samples (50, 100, 200, 400, and $800{\mu}g/kg$) were 78.8-109.3%. Linearity in concentration range of $50-800{\mu}g/kg$ was obtained with the correlation coefficient $(r^2)$ of 0.994-0.999. The intra- and inter-day precision (relative standard deviation; RSD) was between 0.3-12.8 and 0.2-11.7%, respectively. Limit of detection (LOD) and limit of quantification (LOQ) for the investigated tetracyclines were 30 and $50{\mu}g/kg$ depending on egg samples, respectively. This method was reliable, sensitive, economical and suitable for routine monitoring of tetracycline residues in dairy egg.
