  • Studies on the effect of different secondary nutrients in different doses on the leaf yield and biochemical constituents of Terminalia tomentosa revealed that secondary nutrients have promotary effect in increasing the leaf yield and foliar constituents of Terminalia tomentosa. Among all the treatments under study, foliar application of magnesium sulphate (2g/plant, w/v) is the best in respect of leaf yield and biochemical constituents of T. tomentosa. This treatment gave 29.15% increase in leaf yield over control. Chemoassay results further confirmed significant improvement in biochemical constituents. Except crude fibre, moisture, minerals, crude protein and total carbohydrate increased significantly over control.

  • The biochemical nature of the protein constituents of six year old fresh Panax ginseng root was studied. Total protein constituents were extracted with phosphate buffer of pH 7.4, ionic strength of 0.1 and fractionated by ultrafiltration using four different membranes which cut down the materials of molecular weight of 500, 1,000, 5,000 and 10,000, respectively. Each fraction was subjected to ion exchange chromatography using DEAE - cellulose to isolate component proteins. The protein fraction larger than molecular weight of 10,000 was refractionated by the method of ammonium sulfate precipitation. The electrophoresis of the refractionated protein constituents was performed. The amino acid composition of the protein constituents was determined by gas- liquid chromatography. From the results, it could be summarized that eleven different protein constituents smaller than molecular weight of 10,000 were isolated from the fresh Panax ginseng root. At least eleven different protein constituents larger than molecular weight of 10,000 were identified from the electrophoretic patterns. These protein costituents seem to be compounded of all or some of five different subunits.

  • In this study, hexaconazole 5% SC, an ergosterol biosynthesis inhibitor, was tested on groundnut with its recommended ($500\;mL\;ha^{-1}$) and higher ($2,000\;mL\;ha^{-1}$) concentrations under greenhouse conditions in India. Its influence on biochemical constituents of groundnut plants was assessed apart from its disease management potential against late leaf spot caused by Phaeoisariopsis personata (Berk and Curt). Likewise, leaf samples were collected from hexaconazole 5% SC-sprayed plants at different time intervals. Thereafter, their analyses showed considerable differences in the plant constituents, such as chlorophyll, soluble protein, and total phenol contents and the activity of nitrate reductase enzyme. The induction activity of defense-related enzyme, peroxidase, was also analyzed. However, no difference was observed in the isozymic pattern. Moreover, the ground kernels collected from treated plants also showed no difference in the estimated carbohydrate and other constituents.

  • There has been general tendency to explain the traditional ginseng efficacy through the pharmacological and biochemical activities of ginsenosides. However, when we analyze the pharmacological and biological data on ginseng reported yet, we can easily arrive at the conclsion that most of the data on pharmacological and biological activities must have been obtained using impure ginsenoside samples, which should contain some non-saponin constituents as impurities. Based on the above back-ground, the non-saponin constituents of ginseng were studied in our laboratory. Phenolic substances including Maltol, Vanillic Acid, Salicylic Acid, Ferrulic Acid and Caffeic acid and impure ginsenoside samples were found to show strong antioxidant and anti-fatigue activities, while pure ginsenosides were devoid of the activities. Maltol, one of antioxidant components In Korean red ginseng drew a special interest due to its very low pro-oxidant activity. The antioxidant activity of ginseng may be considered as scientific basis for the antiageing activity which was described in traditional medicinal material book as "long-term medication of ginseng will improve bio-efficiency and extend life-span" The lignin components, another non-saponin consitutents, isolated from ginseng extract In our laboratory may eplain the hepato-protective activity of ginseng which has been repeatedly rtaimed as one of the efficacies of ginsenosides. The P-carboline alkaloids isolated in our laboratory as one of the non-saponin constituents of ginseng may play some pharmacological activities which should also be investigated. Present paper will include chemistry and biochemical aspects of the non-saponin constituents of ginseng with special interests for the explanation of traditional ginseng efficacy on modern scientific basis.fic basis.

  • The aim of the present study was to evaluate the effect of the induced heat stress on physiological response and serum biochemical parameters involving glucose, cholesterol, blood urea nitrogen (BUN), non-esterified fatty acids (NEFA), and cortisol in Holstein calves. Ten calves were kept in a climate controlled room (air temperature $37^{\circ}C$ and 90% humidity from 09:00 to 19:00) for three days. Those animals were given a one-day adaptation period. During the treatment period, we measured the skin temperature six times. Following the treatment periods, blood samples were collected before the experiment began (09:00) and at the end of the stress period (19:00). To aid analysis of the biochemical parameters, also we monitored the rectal temperature. The results, exhibited that both rectal and skin temperature showed increase in the heat stress-induced animals as compared with unstressed animals. Moreover, we noticed that the levels of BUN and NEFA increased in the blood serum of heat stress induced animals when compared with un-stressed ones. From these results, we concluded that the physiological and biochemical changes in the calves were induced by heat stress. Hence, the present study findings could be employed as base line data for development of stress reduction techniques in the dairy industry.

  • The effect of supplementation with potassium nitrate on biochemical constituents was analyzed following treatment of last larval stadium. The fat body glycogen and haemolymph trehalosre significantly increased in all the treated groups. The fat body and haemolymph protein also increased significantly in all the treated groups except 500 ${\mu}g$/ml where increased fat body protein and decreased haemolymph protein were not significant. The total lipids, phospholipids and neutral lipids of the fat body increased significantly in all the groups except 50 and 300 ${\mu}g$/ml where the fat body phospholipids increased but the increase was not significant. However the total lipids, phospholipids and neutral lipids are significantly decreased in 500 ${\mu}g$/ml treated group when compared with that of the carrier control.

  • The experiment was designed on 42 non pregnant Black Bengal goat. Out of which 18 were subjected to a superovulatory treatment comprising of eCG and hCG for embryo transfer study. The remaining 24 goats received no treatment and served as control for parameter studied as well as recipient for embryo transfer studies. Important biochemical constituents such as acid and alkaline phosphatase, total protein and cholesterol and inorganic phosphorus were estimated in the follicular fluid of control and treated group and the values were separately recorded for small medium and large size follicle. The results indicated a significant effect on acid phosphotase activity due to size of follicle. The value increased progressively from small to medium and from medium to large follicles. Alkaline phosphotase activity showed reverse trend. Alkaline phosphotase decreased progressively as size increased. The concentration of inorganic phosphorus did not reveal any significant difference between the control and treatment groups and also between the different size follicles. The concentration of protein decreased significantly from small to medium and from medium to large, although no difference was observed between the control and treatment groups. The concentration of Cholesterol in the follicular fluid indicated a significant increase from small to medium and to large follicle. Here also no difference was observed due to treatment. Similar in the composition of follicular fluid in the respect of above mentioned constituents indicated no of super ovulatory treatment on follicular fluid composition.

  • Changes in biochemical constituents and physiological alteration were studied in various intensities (1-5%, 6-15%, 16-30%, 31-50% and > 50%) of leaf spot (Myrothecium roridum) on mulberry leaves and compared with healthy leaves. Chlorophyll, total soluble sugar and total protein were decreased (P < 0.01), but total phenol increased due to pathogen infection. Changes in biochemical constituents showed significant correlation with intensity of disease. Chlorophyll ($r^2$= 0.92), and protein (($r^2$= 0.83) possessed negative while phenol (($r^2$= 0.61) possessed positive correlation. Photosynthetic rate, transpiration rate, stomatal conductance, moisture content (%) and physiological water use efficiency (pWUE) were decreased, but stomatal resistance increased in the infected leaves. Physiological parameters also possessed significant (P < 0.01) correlation with disease intensity. Photosynthetic rate (($r^2$= 0.96), transpiration rate ($r^2$=0.88), stomatal conductance (($r^2$= = 0.65), physiological water use efficiency (($r^2$= 0.88) and moisture content (r = 0.85) were negatively but stomatal resistance (($r^2$= 0.75) was positively correlated to disease intensities.

  • The intradermal injection of Propionibacterium acnes (ATCC 6919) into the ears of female Sprague-Dawley rats produced a chronic inflammation with the formation of acneiform lesions. Inflammation was characterized by more than four times of ear thickness and 2.8 times of ear weight at day 21. Histologically, massive infiltration of neutrophils, macrophage and lymphocytes, hyperplastic epidermis, comedones containing keratin mass and inflammatory materials were observed. Both ginseng saponin and extract from Korean red ginseng significantly redliced the ear thickness and their effects were similar to that of benzoyl peroxide. Ginseng samples and beneoyl peroxide modified lipid constituents of P. acnesinjected rat ear tissues. Even though no marked histological changes in inflammatory lesions were observed in ginseng-treated ear tissues, Korean red ginseng showed a possibility of reduce in the risk of acne development.
