This study was carried out to investigate the effect of Haenginbanhatang extract on the contractile force of the isolated guinea pig trachea smooth muscle and elucidate its mechanism. The results were obtained as follows: 1. The contratile response of the trachea smooth muscle of the guinea pig to histamine was significantly inhibited by Haenginbanhatang. 2. Effects of Haenginbanhatang extract on the contractile response of the isolated guinea pig smooth muscle pretreated propranolol was not significant. 3. The contractile response of isolated guinea pig smooth muscle pretreated methylene blue was significantly inhibited by Haenginbanhatang, 4. The contractile response of the trachea smooth muscle of the guinea pig to prostaglandin F2a was significantly inhibited by Haenginbanhatang. 5.

The antigenicity of the aqueous extract of red ginseng (ARG) was evaluated using the following assay procedures : 1. active systemic anaphylaxis (ASA) in guinea pigs, 2 active cutaneous anaphylaxis (ACA) in guinea pigs, 3 passive cutaneous anaphylaxis (PCA) in guinea pigs, 2.active cutaneous anaphylaxis (ACA) in guinea pigs, 3. passive cutanepous anaphylaxis (PCA) in guina pigs with serum for guina pigs sensitized with ARG and 4. passive hemagglutination (PHA) with serum from guinea pigs sensitized with ARG. 1. ASA : No anaphylaxis reaction was observed in any of the sensitized guinea pigs by elictitation with ARG. 2. ACA : No skin reaction was observed in sensitized guinea pigs after intrademal injection of ARG. 3. PCA in guinea pigs : PCA titer of sera from all the sensitized animals was less than 10 in eliciation with ARG. 4. PHA reaction : When eythrocytes coated with challenge antigen were added to sensitized sera, the hemagglutination titer was less than 1. These results suggest that ARG has no antigenicity under the conditions used. And the dose levels of ARG employed in the present experiment were confirmed not to suppress immune reactions.

A study was carried out to investigate the nutritive value and utilization of three grass species, batiki grass (lschaemum aristatum var. indicum), guinea grass (Panicum maximum) and signal grass (Bracharia decumbens) by growing goats. Eighteen growing crossbred goats $(Anglo-Nubian{\times}Fiji\;local)$ of between 9-11 months of age and pre-trial average live weight of $9.50{\pm}1.60kg$ were divided on the basis of weight to three treatment groups in a completely randomized design. The grasses constituted the diets and they were harvested fresh and chopped into pieces before they were offered to the goats. Chemical composition of the grasses, DMI, body weight gain (BWG) and apparent nutrient digestibility coefficients were measured. The grasses had similar DM content. The CP content of the grasses was in the range of 8.3-11.2%. Crude fiber (CF) content was between 30.9-35.2%. Ether extract (EE) was low with a range of 1.2-1.8%. Nitrogen free extract (NFE) was similar (40.9%) for batiki and guinea grasses, while signal grass had more NFE content (51.1%). The grasses are good sources of minerals (ash). OM content was higher in signal grass while guinea and batiki grasses had similar OM content. The goats on signal grass had higher DMI than those on batiki and guinea grasses (p<0.05). The goats on batiki grass had lower average BWG (p<0.05) than those on guinea and signal grasses. Nutrients digestibility were significantly (p<0.05) higher in the goats on signal grass compared to those on guinea and batiki grasses. The goats on guinea grass were better (p<0.05) in the digestibility of CP, OM, NFE and ME than those on batiki grass. However, goats on batiki were significantly better (p<0.05) in digestibility of CF than those on guinea grass. Signal and guinea grasses had more DCP than batiki grass. DE was lower in batiki grass (p<0.05) than in guinea and signal grasses. There was no significant difference (p>0.05) between batiki and guinea grasses in TON. Data obtained in this experiment demonstrated that signal grass is better than guinea and signal in the nutrition of growing goats in the tropical environment of Samoa. It had the highest nutritive value, better apparent digestibility coefficients which have better growth rate and feed efficiency. In ranking, signal grass was better than guinea and batiki grasses, while guinea grass was better than batiki in nutritive value in the parameters measured. For future pasture establishment in Samoa, signal grass is recommended for consideration because of its higher nutritive value as a replacement for batiki, the most predominant grass.

In order to obtain information on murine model for foot and mouth disease virus(FMDV) type Asia 1, we studied whether guinea pig was a suitable model for studying FMDV. Apparently healthy 3 months old albino guinea pigs and unweaned 3 days old Swiss albino mice were used for this study. Total of 8 guinea pigs were divided into the infected(n=5) and control(n=3) groups. The incubation period of FMDV in the guinea pigs were roughly 2 days and the viremia persisted for 3 days in the guinea pigs. Mice inoculated with the plasma from control guinea pigs did not show any sign of viremia. The plasma were titrated by virus neutralization test using suckling mice as an indicator host. The mean virus neutralizing antibody titers of infected guinea pig at 3 DPI, 4 DPI and 5 DPI were log$\_$10/2.16, log$\_$10/ 3.39 and log$\_$10/ 3.44, respectively whereas there was no neutralizing antibody titer in control group. The difference between the mortality pattern and mean virus neutralizing antibody titer of infected and that of control group at day 3, 4, 5 were statistically significant(p<0.0l).
