The aim of this study was to determine whether viral type HPV-6 and HPV-11 could have influence on the clinical course of recurrent respiratory papillomatosis in children. The detection of viral typing, using the polymerase chain reaction (PCR) was performed on papilloma biopsies of 36 patients at ENT Hospital HCM City from 3/2000 to 3/2004. HPV-6 was detected in 17 patient's biopsies and HPV-11 in 19 biopsies. After the findings, patients infected by HPV-11 have more aggressive than patients infected by HPV-6 (73.7% vs 29.4%; p=0.008). Patients with HPV-11 have higher prevalence of tracheotomy and shorter interval time between two operations than patients with HPV-6

By synthesizing and analysing poisoning analyses from 1996 to 2000 at Hai Phong Viet Tiep Hospital found an increasing incidence of insecticide and raticide poisons. Incidence of insecticide and raticide was 21.18% in 1996, in which raticide rate was 5.08%, raticide rate was 20.11% in 2000, there were a noticeable rate of raticide poisons without knowing the origin of the raticide in chinese (called chinese raticide). The poisoning analyses played a considerable role in giving first aid for poisons in general and for insecticide and raticide poisons in particilar

This study attempted to delineate the relationship between juvenile laryngeal papillomas (JLP) and genital HPV infection in their mothers on 36 pediatric patients JLP with HPV(+) and 14 their mothers with HPV detection from cervical swab at ENT Hospital HoChiMinh city, from March 2000 to March 2004. The results showed that: the rate of genital HPV(+) is 85.7%; the similarity between child and mother genotype is 100% with HPV-11 and 75% with HPV-6. It could have the possibility of HPV transmision from mother to child in recurrent respiratory papillomatosis

Naturenz, a mixture of plant oxydase, protease, natural anti-oxydants, aminoacids and vitamins has been used for treating dioxin exposed patients. This preparation can improve the patients status. An icrease of SH-group, of total hem content and of anilin hydroxylase acitivty in blood, a decreasing of urine urobilinogen was notified on patients after administration

PDP has been verified to enforce the body’s immune system by improving both cellular immune and humour immune. Statistical analysis of blood cell quantity of rabbit before, during and after taking PDP showed that erythrocyte, leukocyte and platelet were proliferated significantly, especially leucocyte and platelet. G-globulin in the serum of white mouse tested by the dose of 5mg/10g and 10mg/10g of body weight has been found to increase significantly, the rate of albumin/globulin reduced. The same result also has been observed in the white sewer rat and rabbit. The effect of PDP on the grease was investigated on Tam hoang chicken. It was found that there was a reduction of the rate of the grease over body weight when the chicken was taken PDP. Electrocardiogram of rabbit serum, which was recorded at 2mV and 50cs/min proved that PDP did not cause any harmful effect on heart. Besides, no physical disease occurred on heart action

One method to determine the content of chitosan present in Pokysan cream has been developed. Chitosan was separated from Pokysan by dissolving the cream in acidic solution, extracted by chemical mixtures of I and II, which were prepared by laboratory of polymers in medico – pharmacy, and then collecting the precipitate of chitosan in the alkaline medium. This precipitate was then qualified by Lugol reagent and IR spectra. Collected chitosan precipitate was also qualified and quantified. These results proved that chitosan has been included in Pokysan cream and our method is confident

A study on 90 people ( 62 male and 30 female) who had history of bone fracture due to serious trauma was conducted in Friendship Hospital. The result showed that: the age and BMI is equivalent between two groups. The bone mineral density in males is higher than that in females, the bone mineral density is highest on neck of femur and lowest on trochiter. The rate of osteomalacia on the upper part of femur was 31.5%. The density of the neck of femur in male group is higher than female ones. Weight, BMI and sport playing are factors related to crease bone density. Age, smoking and alcohol drinking are factors that lessen the bone density. For the elders, it is nesesay to measure the bone density in order to have preventive methods and appropriate treatment, avoid bone facture later.

Previous papers have reported that polyphenols from green tea (Camelia sinensis L.) were useful for controlling dental caries. This study examined the effects of the ethanol total polyphenol extract (CX) of green tea leaves on dental caries causing Streptococcus mutans. CX showed to inhibit the glycolysis, biofilm formation and respiration of S. mutans. At the concentration of 0.05%, CX suppressed 30% oxygen consumption in glucose excessive medium, totally inhibited NADH oxidase activity and killed the bacteria with D value of about 13 minutes. The combination of 0.025% CX and 0.25 mM NaF blocked pH drop during glycolysis. Polyphenols from green tea leaves inhibited therefore the adherence of S. mutans in vitro and proved to be effective against dental caries.

The study was carried out at Hung Vuong Hospital in 1998 to compare vaginal misoprostol with extra-amniotic balloon to induce abortion in second trimester. Patients were received either 800mcg misoprostol vaginally (n=87) or 500ml of 0.9% NaCl solution inserted into extra-amniotic cavity (n= 93) for induced abortion. Vaginal misoprostol was repeated 24-hourly for maximum of three times. The abortion rates were 98.9% and 96.8% for misoprostol and balloon group, respectively. A second attempt was need in approximate one third of patients in misoprostol group and 10% in balloon group. Side effects of misoprostol were mild and transient. Vaginal misoprostol is as effective as balloon for induced abortion in second trimester. Misoprostol is cheap and easily stored and used. Vaginal misoprostol could be considered as an alternative to balloon for induced abortion

Filariasis mosquitoes and susceptibility of Cx. quinquefasciatus and Cx. vishnui to insecticides were investigated in September 2004 and May 2005 in Khanh Trung commune, Khanh Vinh district, Khanh Hoa province. Twenty two mosquito species belonging to 5 genus have been found, of which the primary vector of W.bancrofti filariasis was captured with a high density, while vectors of B.malayi was found in a lower density. A total of 805 mosquitoes of 6 species (An.barbumbrosus, An. vagus, Cx.fuscocephala, Cx.quinquefasciatus, Cx.tritaeniorhynchus and Cx. vishnui) were dissected. None of them were positive with microfilaria. Cx.quinquefasciatus was found highly resistant to lambdacyhalothrin, alphacypermethrin and malathion with the mortalities of 11 %, 21%, and 60%, respectively. Similarly, the mortalities of Cx.vishnui were 19.76%, 23.83% and 13%-17%, respectively.
