Essential oils of leaves and trunk barks of Cinnamomum cassia J.S. Persl. of two different origins (Quang Nam and Thanh Hoa) have been grown in Phuoc Son district, Quang Nam province were selected and analyzed by GC/MS. The barks of Quang Nam origin gave higher oil percentage and cinnamaldehyde content (6.80% and 88.74%, respectively), while those of Thanh Hoa origins were only 0.65% and 67.39%, respectively

Clinical trial was carried out on 30 patients (28 females, 2 males at the age of 18 and 60 years old) with low blood pressure (systolic blood pressure <90mmHg and/or diastolic blood pressure <60mmHg) with other clinical symptoms such as headache, dizzy, fatigue, and insomnia were treated by 'Sinh mach Bao nguyen' tea- a herbal formula of traditional medicine. After 30 days of treatment, 93.33% of patients have higher blood pressure. Some clinical symptoms reduced significantly. There was no side-effect

The study had been conducted in 85 patients aged from 22-49, who were diagnosed as cervical erosion to find out the effect of cryosurgery method. Results: this method was effective in treating cervical erosion; 80% of the patients recovered after the 1st time treatment and 20% in the 2 nd times. The percentage of the recovery related to diameter injuries. This method did not cause any serious complications but some light complications such as disordered menstruation (17.6%), menorrhagia (11.8%), backache or lower backache (5.9%), appendage inflammation (4.7%). After the treatment, 8.2% of these cases are able to get pregnant and give birth as common

With the method of water vapor distillation using the "modified apparatus for quantifying essential oil" of Ha Noi college of Pharmacy the essential oil was analysed by GC/MS. Results found essential oil in all organs of the plant such as root, stem, small branch and leaf, but the most was in leaf. The essential oil is a yellow liquid, heavier considerably than water. In the above- ground organs, there is almost 98,45%-99,03% of methyl salicylat. In the root, this content is lower, an addition with other components such as delta- tetradecalaction caryophylen oxid, nootkalon

The study involved 115 patients who was diagnosed with cervical disc herniation by MRI at the Military Hospital 108 and ViÖt - §øc Hospital from January 1997 to July 2001. Among these, 82 patients underwent cervical discectomy and 33 patients were treated by medication. 15 patients were studied retrospectively, and 100 patients were studied prospectively. Mean age of patients was 49.15 years (ranged from 27 to 78). 93 men, 22 women. The results showed that 1-segment disc herniation was most common (53.9%), followed by 2-segment herniation. 3-segment herniation was seen only in 10 cases. 100% of patients in operative group have post-operative diagnosis as same as MRI diagnosis. 87.5% of patients have excellent and good outcome at 1 week after operation. It was suggested that the diagnosis of cervical disc herniation and operative indication was appropriate.

Participants in this study were 28 patients who were diagnosed with cervical disc herniation by magnetic resonance imaging (MRI) at the Internal Medicine Department of the Military Hospital 108 between July 1997 and July 2001. Mean age of patients was 47.54 years, ranged from 34 to 66. Males: 19, females: 9. It was found that that out of these, 10 patients had 1-segment cervical disc herniation, 15 patients had 2-segment cervical disc herniation, and 3 patients had 3-segment cervical disc herniation. Total of herniated cervical discs was 49 per 28 patients. Good and moderate results of nonoperative management were achieved in 84% of root syndrome sub-group, in 33.3% of myelo-root syndrome sub-group and in 78.57% of total group. Internal management included cervical immobility, analgesics, non-steroid anti-inflammatory drugs, vitamin B, muscle dilation, sedation, cervical block and manipulation, and physiotherapy.

The new apparatus is improved on the base of the apparatus for volatile oils determination of the “Methode I” described in the Vietnamese Pharmacopeia I (1971). It includes in 3 principal parts: a shortneck 0.5-1 liter flask, a cold condenser and a tube adapter, which binds the flask and a condenser. Tube florentin, which is suspensed in the tube adapter, is graduated in 2 parts: the superior part to 0.1ml and the inferior part (smaller) to 0.02ml. The improved apparatus is simple, good closed and permit to determine exactly the volatile oils in the drugs.

Two samples Amomum from NinhThuan were investigated. They were identified as Amomum thyrsoideum Gagnep. and Amomum longiligulare T.L. Wu. The leaf-oils and fruit-oils from two varitae were analysed by GC/MS. 14 compounds were detected in the leaf-oils and 19 in the fruit-oils. The main components in the leaf-oils, from A. thyrsoideum were cis-Ocimene (39.03%) and -Pinene (41.55%), from A. longiligulare were -Pinene (22.50%) and -Pinene (61.77%). The main components of the fruit-oils were camphor (34.29-35.77% and 44.46%) and bornyl acetate (41.22-43.25%, and 26.62%). The fruits from the two varieties are rich on essential oil. The amount of oil were 3.0-3.75%

Investigatetion of the fruits and leaves oil of Litsea cubeba (Lour.) Pers. wild growing in the moutain areas in Ba Vi district, Ha Tay province. The major components of the fruits oil of Litsea cubeba (Lour.) Pers. is citral, which includes of neral (citral b) and geranial (citral a) with content over 65% equivalent in some Northern provinces. Fruits and leaves oil analysis were carried out by a combination of capilarry GC and MS. The main components of the leaves oil are linalol (over 85%), 1.8-cineol (-50%), sabinen (10-15%) and -terpineol or -terpinyl acetate (10-20%). This plant in Ba Vi has many biochemical diversification, that is also a character of Lauraceae as Long nao, Vu huong.

Materials and methods: Fruits and leaves of Litsea cubeba (Lour.) Pers. were collected in August 2001. The essential oil analysis was carried out by combination of capillary gas chromatography and mas spectrometry. Results: 16 constituents were identified in the fruit oil, and 27 in the leaf oil. The major components of the fruit oil were geranial (46.83%) and neral (38.77%). The monoterpenic hydrocarbon compounds occurred in a very low amount, except l-limonene (2.14%). The other oxygenated compounds as well as the sesquiterpenic compounds were only about 1%. The major constituents of the leaf oil were cis-ocimene (42.84%) and cineole (10.54%). In addition, there were: linalool (2.07%), terpinene-4-ol (3.65%) and alpha-terpineol (3.65%). The monoterpenic hydrocarbon compounds were found at the level of 74.56%.
