120 healthy subjects were selected and divided into two groups to study the cutaneous conductivity at 12 couples of Yuan point, group 1 including 60 subjects aged between 21 to 25 (30 males, 30 females), group 2 including 60 subjects aged between 50 to 67 (30 males, 30 females). The results: there was no difference in cutaneous conductivity at 12 couple of Yuan point of the lest and right body in both groups of ages and sexes. In female, cutaneous conductivity at 12 couple of Yuan point were diferent depending on menstrual cycle, considerably lower in the latter haft of the cycle compared to the first half of the cycle. In the same age group, cutaneous conductivity at 12 couple of Yuan point in male was lower than that in female. In the same gender group, cutaneous conductivity at 12 couple of Yuan point of the group 1 was lower that of the group 2

Study on chemical components of Fissistigma capitatum Merr. ex Li (scientific name was defined by Bachelor Ngo Van Trại, National Institute of Medicinal Materials) collected at Sa Pa in June 2003. 600g of dried and grinded leaves and branches were leached with methanol:water (95:5) at room temperature. Methanol solvent was distilled at decreased pressure. The remained fluid was extracted many times with n-hexane, ethyl acetate and butanol. N-hexane was vacuum-evaporated, which collected 11.2g sediment. N-hexane sediment fluid was refined by silica gel chromatographic, which collected compounds 1 and 2. The structure of compound 1 was taraxerol, compound 2 was 16-hentriacontanone with white crystal form when comparing with document data. This compound named palmitone and previous isolated from the leaf of Annona diversifolia

Lasia spinosa L. (Araceae) has been used in the Vietnamese traditional and folk medicine for treating sore throat, cough, nephritis, rheumatism, liver diseases (hepatitis, ascitic cirrhosis), sequels of malaria and skin diseases. In this primary study on chemical constituents of Lasia spinosa L., leaf powder and root powder of Lasia spinosa L. were leached with n-hexan, CHCl3 and MeOH solvents, three times for each solvent. 5 compounds including p-hydroxy benzaldehyde, acid p-hydroxybenzoic, acid 3-hydroxy-4-methoxy benzoic, 2-(4’- methoxyphenyl)-ethanol, adenine were isolated by spectroscopic methods

Objective: To evaluate the decrease of pulmonary function in patients with respiratory distress in order to help physicians give appropriate indication of oxygenotherapy at home with appropriate doses. Subject: 37 patients and 20 healthy people in control group. Results: There isn't any change in heart rate, FEV1, walking distance, and SaO2 after walk test in healthy people. Elevating in radial artery pulse (+50 in male, +55 in female) represents increasing the need of oxygen during exercise. SaO2 decreases significantly. PaCO2 reduces. Patients can't walk as long as the healthy. Evaluting SaO2 decrease after walk test can help physicians give appropriate indication of oxygenotherapy at home with appropriate doses

Aspirin, analgine, and paracetamol are long-standing effective anti-inflammatory painkiller agents. This three agents were mixed with herbal products with standard level is a complex process. The authors introduced following steps: analgine with process having median productivity by 58.20%, aspirin with Stass-Olto process having median productivity by 83.90%, paracetamol with process having median productivity by 73.30%. This can identify reliably appearance of aspirin, analgine, and paracetamol in herbal products. Aspirin achieved highest productivity

A random study on skin temperature change at 12 couples of Yuan point was carried out on 120 subjects. These subjects were divided into two groups: 60 subjects with duodenal ulcer and 60 healthy subjects served as control. Results: There were difference in skin temperature of bilateral Thai xung point in both male and female with gastric-duodenal ulcer (P<0.05-0.01). Temperature of 12 couples of Yuan point in this group was higher than those in control group (P<0.05-0.001)

Study on 33 asthma patients and identifying maximum expiring volume per second and medium flow between expiring stage of living volume from 25% to 75% in asthma patients without severe stuffy treated at Bach Mai hospital in 2000. The results: there was no difference of sex in asthma. 24% of patients with childhood asthma; 0.6% of them with asthma over 20 years and 30% of them with asthma from 10 to 20 years. After treatment, medium expiring gaz flow at the middle of expiring stage at 25% to 75% of living volume decreased down 50.8% compared with theory value. 48% of patient with mixture ventilation disorder. 40% of patients with obstructed ventilation disorder, 24% of patients with pheriperal obstructed ventilation disorder

In 1999-2000 year period at Bach Mai Hospital, on 26 patients sufferring from systemic lupus erythematosus (SLE) with nephrotic syndrome . SLE developed with higher incidence in women than in men (23 versus 3). Proteine and albumine blood level reduced significantly in comparing with control. Through urine, a quantity of proteine of 4,2g/24 hours lost . Blood lipid of all lipid components enhanced significantly in comparing to control. HDL-C level reduced a little, only in severious patients.There was an inverse proportional relationship between CT,LDL, with HDL; between HDL and CT with albumine contents in plasma

In the year 1999 at Bach Mai Hospital, serum CRP level was quantified on 21 patients with allergic bronchial asthma without bacterial infection and 38 associated with bacterial infections.In patients of infected allergic bronchial asthma the positive rate of serum CRP was 115,2+/- 6,03 in average, higher than in non infected ones. After treatment, CRP level reduced with statistical significant. In 90,48% of cases of simple allergic bronchial asthma, white blood cell count was normal, while in 92,12% of infected cases, white blood cell count enhanced. There was a positively proportional relation between diverse indices determining inflammative status in the group of patients with infected bronchial asthma

The water extracts of Macrotermes anadelei and Polyrachis dives were shown to improve the memorization power of rats at the dose of 10 mg/kg body weight. After the 21-days training for one trial learning avoidance test, the time the rats remained in the bright chamber was reduced to 47.2% for those received M. anadelei, and 43.6% for P. dives, not significantly lower than Ginkgo biloba (50.6%). In Morris Water Maze, both those extracts were also proved to boost the process of learning and memorization in mice.
