Lethal component of the Naja kaouthia venom had been purified and used as antigen for producing antiserum according to an immunization protocol aiming to be efficient in the production of high affinity antibodies. A strong response was observed on all six immunized horses and tolerance to the antigen did not occur. All antitoxin sera obtained protected against lethality due to the entire venom. The potential production of these six horses is estimated to 4,300 doses/year compared to the estimated national need of 4,800 doses/year for a population of 80 millions.

Orange agent/Dioxin is very toxic chemical. It has still exist and harmful affected on persons living in many areas of South VietNam since America chemical war. This study is aimed to evaluate the effects of Dioxin residue on changes of serum FT 4, T3, TSH in 318 persons exposed to the toxic. RIA and IMA assays were used to measure serum concentrations of the hormones. The results of the hormones from persons exposed to Dioxin were: 1. Serum concentration of FT4 is 9 to 25 pmol/L and significant lower in comparison with those of control group living in Hanoi. Serum concentration of T3 is 1 to 3 nmol/L and not significant lower in comparison with those of control group living in Hanoi. Serum concentration of TSH is 0,25 - 5 mUlL and not significant higher in comparison with those of control group living in Hanoi. 2. There are significant differences in serum FT4, T3. TSH concentrations between communes sprayed Dioxin in the war. 3. Abnomal ratios of serum FT4, T3, TSH concentrations of persons exposed to Orange agent/Dioxin are higher than those of control persons living in Hanoi.

The quantitative analysis of the concentration of serum calcitonin was carried out in 29 normal people with ages of 18-50. The results: this is a method with the high confidence; the average concentration of serum calcitonin is 5,74 Pg/ml; the minimal concentration at 0,00 commonly found, the maximal concentration is 22,6 Pg/ml; the distribution was not same as the rule of Gauss so the medial figure was 4,98pg/ml as preparesentative; there is no different of this concentration between male and female.

The evaluation of serum viscosity contributes to the diagnosis of some hematopathology, cardiopathology. A study on 303 healthy persons with ages of 18-81 in Hanoi was carried out to determine the Vietnamese serum viscosity. The results have shown that the serum viscosity found in the normal people was 9.180.47 (1.52-2.45). There is no significant different of the serum viscosity between men and women. The serum viscosity is gradually increased as increased age.

From 2001 September to 2002 August, 566 serum samples of 5-6 months pig at Hoai Duc district, Ha Tay province were supervised. Results showed very high frequency of JE infection among pig population during epidemic season with the percentage of positivity was 82% in June. By contrast during another months of non-epidemic season, the frequency of JE infection among pig population was very low, with the percentage of positivity was between 1.96% and 14%

42 samples of serum of Rattus novergicus in Ha Nam province were tested for Hantaan virus by ELISA and IFA methods. Results: 4/42 samples (9.25%) had anti-bodies against Hantaan virus. With IFA method, 2/4 samples were confirmed again. It is necessary to supervise serum of people in community and unknown fever

After the use of improved purification procedure, the quality of 10 lots of rabie antiserum (IVAC) were assessed. Average potency reached > 200 IU/ml, the protein content was 57.85 mg/ml

4 groups of antiserum were met the inquiry to make strongest immunized response and to produce most antibody against Sh.flexneri. Produced antiserum has a high specificity and a possible identificity to detect correspond antigene. It met the physical criteria, having good sterility, specificity and sensitivity. The preparation was stable after 24 months follow up. It can be used to differentiate the subgroups of Shigella

21 children aged 1-15 suffering from 10-25% body surface burn infected with pyocyanic bacteria were treated at the National Institute of Burn from April to October 2002. Burn lesions were divided into 2 zones with similar superficilit and depht. On the zone A, antipyocyanic serum was applied, and zone B, silver sulfadiazine 1% (SSD1%). Results showed that entipyocyanic serum had got the effects of secreting reduce, anti inflammation and deodorizing and decolorizing of the burn, stimulating the epithelial processing, reducing the pyocyanic bacterial infection frequency from 100% in the first examination to 7.14% in the 3rd examination and the count of pyocyanic bacteria from 22.12  0.07 x 104 to 2.44  0.01 x 104. The duration of treatment in shallow burn of II, III grade (7.2  0.6 days versus 8.5  0.2 days) and in deep burn of III grade (14.5  0.7 days versus 16.5  0.6 days)
