40 patients with bronchial asthma in Bach Mai hospital from 6/1998 to 5/1999 and 31 healthy people without allergy. Methods: finding the allergic history and skin test. The results: 52.5% of patients had his own allergic history; 42.5% of patients had a family history; 37.3% of patients had positive skin tests to foreign bodies of house dust mite; 32.5% of patients had allergic antibody against foreign bodies of house dust mite was more 30%. Among methods of specific diagnosis of allergy, there was a close relation between skin test and reaction of decomposition of mastocyte.

Loranthus parasiticus (L.) Merr. Loranthaceae (Vietnamese name is Tang ky sinh) was a traditional medicinal herb for treatment of back pain, hypertension, lack of sleep, etc. The chemical analysis confirmed the Loranthus parasiticus (L.) Merr. extract contained flavonoids, adjuvant heart glycosides, antraglycosids, tannin pyrocatechics and organic acids. Total flavonoid content was 0.57%. The pharmacological experiments in mice, dogs, isolated ears and isolated ileum of rabbits have revealed that the Loranthus parasiticus (L.) Merr. extract had antihypertensive, sedative and vasodilator effects. In addition, Loranthus parasiticus (L.) Merr. decrease ileum's mobility of rabbits and had a low acute toxicity

Some new antimalarial water soluble derivatives of artemisinin were prepared by etherification of dihydroartemisinin with appropriate aryl alcohols. They are artelinat and metaartelinat. Influence of catalists and solvent on the etherification and the antimalarial activity of them as well as artesunat were studied.

55 patients with perforated duodenal ulceration received the vagotomy as method of Taylor. Patients admitted to hospital after perforation 12-14 hours. Patients had no shock, gastrointestinal bleeding or pyloric stenosid. The results have shown that the operation as method of Taylor and Hill barker did not increase the risks. There had no intraoperative and postoperative serious complications. The method maintains the motor function of stomach with latarjet stem. This was simple method that easy to implement.

A restrospective study on 484 patients with the perforated duodenal ulceration has shown that male/female:9/1, patients with ages of 20 -50: 77% (youngest: 14; oldest: 80), no history of the duodenal ulceration: 33.34%, operated prior to 12 hours from the first pain attack, premature ulceration: 24%, moderate fibrosis: 14%, corn fibrosis: 62%, possitive clotest: 83%, simple surgical: 70%, mortality rate: 1.5%, rupture in stitching position in the method of stitching the perforated position, relapsed rate of ulceration in the stitching the perforation position and removal surgery of 2/3 stomach, Xth nervecutting as method of TALOR and method of HILL-BARKER were 72%, 3.5%, 34% and 8%, respectively. This study indicated that it should radically operate in the first phase in order to reduce the patient‘s risk provided that having no risk factors.

A study on the prostatic samples from 2 groups of patients with prostatic intra epithelia neoplasia, group I- patients in the post-telecommunication hospital and group II- patients in the Saint Vincent. The researcher found that there was no significant difference of ages between 2 groups, the prostatic hyperplasia frequently occurred in persons with ages of 60-65, while prostatic epitheliama frequently occurred in patients with ages of 80-85. The high grade lesion of prostatic intra epithelial neoplasia in the group I was less than this in the group II. The prostatic intra epithelia neoplasia combining with prostatic epithelioma in the group I was lower than this in group II.

The osteomyelitis and arthritis are common surgical emergency. During 10 years(from 1988 to 1997) we operated 214 cases with 143 males and 71 females with Haematogenous osteomyelitis by technique of drilling bone and irrigation of antibiotic solution, surgical drainage of subperiosteal pus. The purpose of those papers are to evaluate method of drilling bone with irrigation of the medullar canal by antibiotic solution and to examine some early signs of osteomyelitis in children. 115 patients were operated by drilling bone with irrigation of antibiotic solution, and 69 patients of them were operated by drainage of subperiosteal pus. The early signs of heamatogenous osteomyelitis with fever, localized paint, swelling, tenderness and warm are usual.

Dislocation of the shoulder after intramuscular injection antibiotic(s) is rare and this conditon was limit described in literature. Our purposes were: (1) determining the clinical symptoms, X-ray and CT findings; and (2) determining the indications and the surgical technique and evaluation of the surgical result. Material and methods: 62 children (29 females, 33 males) aged from 4 to 16 years were included. Clinical and X- ray findings were analysed for anterosuperior subluxation or dislocation of humeral head. The patients were operated to release of origin or insretion of the mild Deltoid muscle or Z plasty of this one. Surgical procedures provided good result in 75.3 percent, fair in 24.7 percent and there were no infection or neuromuscular complication in these cases. Conclusions: This condition always resulted from repeated Deltoid intramuscular injection. The surgical treatment with resection of fibrous portions constantly gives relief of symptoms and provides good function.

Studying method of manufacture of post-harvest Flos Sophorae showed that: 2 methods can be used to process Flos Sophorae. The first, B2 traditional method: roast 15 - 25 minutes and then dry at 60°C. The advantages of this method are simple, easy to use and have good results. The second, D method is soaking Flos Sophorae in 7.5% salt solution in 15 minutes, dry, roast in 20-25 minutes, drying at 60°c. This method is more complex but have better results. D method could be used at the industrial scale

Uremic neuropathy is a distal sensorimotor polyneuropathy caused by uremic toxins. The severity of neuropathy is correlated strongly with the severity of the renal insufficiency. The electrophysiological study is a sensitive test for diagnosis of neuropathy in patients with uremia. Objectives: (1) To assess the clinical characteristics and (2) to describe the electrodiagnostic abnormalities of neuropathy during the haemodialysis. Patients and method: Clinical examination, motor and sensory nerve conduction measurements and an H reflex study (via the Nicolet EMG machine) were performed in 32 non-diabetic uremic patients (16 men and 16 women, mean age 43.5+2.29), who were all treated with chronic maintenance haemodialysis. Results: The incidence of neuropathy in haemodialysis patients was 68.8% on clinical examination and was 96.9% on electrophysiological study. The abnormalities in clinical findings were altered motor-sensory function in 62.8%, predominantly impaired sensibility in 50%, loss of tendon reflexes in 37.5%, symptom of restless legs in 46.9% and carpal tunel syndrome in 9.4% of patients. In the electrophysiological parameters, compared with Vietnamese healthy index, the nerve conduction velocity of all tested nerves was decreased significantly (p<0.05), the highest abnormal rates was the sural nerve (75%), the tibial nerve (71%) and the peroneal nerve (69.4%); H-reflex was also significantly prolonged in 42.9%. Conclusion: The most haemodialysis patients showed clinical and electrophysiological evidence of uremic neuropathy. Electrophysiological findings showed more abnormalities than clinical examination for neuropathy showed on hemodialysis patients.
