The effect of Kundur (oleo-gum resin of Boswellia serrata) and its fractions viz: methanol soluble (MS) and methanol insoluble (MI) were investigated on mercuric chloride induced nephrotoxicity in rats. The animals of group I and II were administered with 1% carboxymethyl cellulose (CMC) (1,000 mg/kg, p.o.) and the animals of groups III, IV and V were administered with Kundur (1,000 mg/kg, p.o.), MS (650 mg/kg, p.o.) and MI (350 mg/kg, p.o.) respectively for ten days. On 10th day a single dose of the mercuric chloride (3 mg/kg, 5.c.) was also administered to all groups except the group I which received only 1% CMC (10 ml/kg, p.o.). After two days of mercuric chloride administration the blood samples of each animal were collected and analyzed for blood urea nitrogen and creatinine concentration. Rats fed with Kundur and MI fraction showed a significant prevention in the rise of serum markers while MS failed to prevent the rise of these serum makers. These results suggest that Kundur and MI fraction may have potential to reduce the nephrotoxicity in rats.

Twenty five albino rats were divided into five groups for conducting this experiment. The first group was for positive control (Vitamin C, ascorbic acid), the second group was of Panax ginseng (10 mg/kg body weight) treated group after bio-activity assay, the third group was of mercuric chloride treated group (0.033 mg/kg body weight) based on calculating $LD_{50}$ 9.26 mg/kg body weight by probit analysis, the fourth group was of mercuric chloride (0.033 mg/kg body weight) followed by Panax ginseng (10 mg/kg body weight) and the fifth group was Panax ginseng (10 mg/kg body weight) followed by mercuric chloride (0.033 mg/kg body weight) treated group. The interval between intake of Panax ginseng and mercuric chloride was of 2 hours in groups, fourth and fifth respectively. Comparative free radical scavenging property of Panax ginseng was studied under three in vitro models (role model for calculating scavenging activity) viz. DPPH method (hydroxyl free radicals), Nitric oxide method (nitrile free radicals) and Lipid peroxidation (mercury free radicals).

The clastogenic effects of the diesel emission particle extract (DEPE), mercuric chloride and lead acetate were examined by the mouse bone marrow micronucleus test. DEPE had a potent clastogenic effect by intraperitoneal injection with dose-response between 100 and 300mg/kg b.w.. Mercuric chloride and lead acetate also gave a clastogenic effects but mercuric chloride only had a dose-response between 1 and 3mg/kg b.w.. When DEPE was administrated with mercuric chloride or lead acetate, the frequency of micronucleated cells was slight but not significant increase in comparision to a single treatment with DEPE alone.

To investigate the effect of mercuric chloride on the pectoral muscel cells during chick embryogensis, chicken embryos were treated with mercuric chloride. Monoclonal antibodies against myosin were prepared for the localization of differentiation of thick filaments detected by the use of protein A-gold complex as a cytochemical marker. The effect of mercuric chloride was appeared not only to be ascribed with the reduced formation of myofibrilogenesis but also associated with induced change of morphology by the inhibition of protein synthesis.

Experiments were conducted with goldfish exposed to various levels of mercuric chloride(control group) and mercuric chloride with chitosan (experimental group). Dilutions of these two solutions were made in the concentration ranges 0.6 to 1.0 $mg/{\ell}$ and 1.2 to 2.0 $mg/{\ell}$, respectively. Fifty percent lethal concentration of mercuric chloride($LC_{50}$) for 48 hours with the species was between 0.6 and 0.7 $mg/{\ell}$. Exposure of goldfish to mercury produced a marked, dose-dependent mortality with elevation of concentration (P<0.05). However, at each concentration of mercuric chloride treated with chitosan, mortality decreased significantly compared to control group (P<0.05).

To investigate the effects of mercuric chloride ($HgCl_2$) on the differentiation in the cerebral neuron of chick embryo 7 days, the ultrastructural changes in nerve cells injected with a various doses of mercuric chloride were observed with transmission electron microscope. The enzyme activity of the some dehydrogenases, and adenosine triphophate (ATP) were also analyzed. The results obtained are as follows; The ultrastructural changes in 1.0mg-injected group, the nuclear envelope were irregular, and the RER, Golgi complexes and mitochondria were not well developed. In 2.0mg-injected group, the nuclear envelope were partly destroyed or detached, and mitochondria were decreased in number and their cristae were destroyed, too. The RER and Golgi complexes were less developed than those of the normal groups. In general, the activities of dehydrogenases were declined by increasing the dose of mercuric chloride. Lactate dehydrogenase (LDH) activity fatted to below 85% of the normal group in 1.0mg-injected group, and 69% in 2.0mg-injected group. Malate dehydrogenase (MDH) activity was decreased greatly to 76% in 2.0mg-injected group. Succinate dehydrogenase (SDH) activity fatted to 85% in 1.0mg-injected group, and 74% in 2.0mg-injected group. ATP content in 1.0mg-injected group was almost near to the normal level, but it was increased significantly in 2.0mg-injected group.
