A new spectrophotometry was described for the simultaneous analysis of pseudoephedrine sulfate-Ioratadine combination. The derivative spectrophotometry dA/d values were read at zero-crossing point. Mean recoveries were found to be more than 98% for these compound in mixture. The procedure does not require any separation step and proven to be rapid, simple and accurate for determination of the mentioned sample or corresponding multi-component mixture

In the study, 25 consecutive eyes of 25 patients (21 men, 4 women; mean age: 45 ± 8.5 years; range 30 to 58 years) with central serous chorioretinopathy were examined with optical coherence tomography (OCT) during acute phase and after the resolution of the retinal detachment. Cross-sectional retinal images through the center of the fovea were obtained from all eyes by OCT. The retinal thickness at the fovea center was measured. All of patients were conducted fluorescent angiographies. In the acute phase, neurosensory retina was thickened within the area of serous retinal detachment in all 25 eyes. The retinal thickness at the center of the fovea during the acute phase (range, 162 to 273µm; mean ± SD, 192 ±18 µm) was significantly thickened in comparison with that after resolution (range, 98 to 149 µm; mean± SD, 117±12.7µm). The retinal pigment epithelium was focally detached in five eyes

From Nov.2001 to July 2003, the analysis of chromosomes of 92 patients with CML evealed the metaphase figure of chromosomes of bone marrow cell which will be obtained easier than blood, but the blood is better Philadelphia chromosome found in 91,25% of cases of success.There is no significant difference between male and female subjects as between various age groups

This study was carried out in 47patients (47 eyes) with traumatic optic neuropathy admitted Cho Ray Hospital from March 2003 to March 2004, among them 39 cases were treated by high-dose corticoids. The percentage of traumatic optic neuropathy was 0.32% of all head trauma cases. Among 47 patients, there were 44 males, 3 females, mean age: 30 years old, lesions were in 18 right eyes and 29 left eyes, traffic accidents were in 46 cases (97.9%), mainly were motorcycle accidents. The mean duration for finding lesions is 20 hours and mean duration for treating is 37 hours. Visual acuity was severely decreased: 76.6% patients with no light perception, 85% patients with no light perception and light perception. Concomitant traumas included injuries in ear, nose and throat trauma (51.1%), teeth (40.4%), head (38.3%). CT scan finding revealed fractures of orbit in 19 cases (40.4%), of optic canal in 6 cases (15%). Treatment with high-dose corticoids (methyl-prednisolone IV 500mg-1999mg a day) for 39 cases had more effective than no treatment or low-dose corticoids (< 500mg) in 8 cases. The percentage of vision recovery in high-dose corticoid group was 38.5%, with 2 cases had complications of high glycaemia (5.1%). Early treatment within 8 hours after trauma could give higher rate of recovery. Prognostic factors for no recovery included vision acuity after trauma was no light perception, 4-grade soft tissue lacerations and no response after 48 hours of high-dose corticoids. In the optic neuropathy, the rate of vision recovery in high-dose corticoid group was 38.5%, and treating by high-dose corticoids had few complications, more effective than low-dose corticoids (p<0.05)

The fourth bronchial pouch fistulae is the lesion of the fourth bronchial-pharyngeal duct in development of the embryo. 20 cases of this disease were diagnosed, operated and followed-up in the institute of ENT, from 1995 to 1997. 11 females and 9 males were affected; It manifested itself by recurrent episodes neck abscess, especially on the left side (95%). 13 fistulous tracts were found on operation with 86% of retrocartilaginous course.

Bronchial cleft abnormalities are the results of defects in development in neck area of the embryo. They are uncommon clinical problems that can be difficult for diagnosis and treatment. A serie of 24 cases observed in the institute of ENT (1995 - 1999) with bronchial cleft fistula are debated. The primary symtom of 2nd bronchial cleft fistula is a congennital latero-cervical fistula, but the primary symtom of 3,4 grade bronchial fistula is a tumefaction located at the middle third of neck. Complete resection of these fistulas avoid relapse

On studying 147 hemoglobin electrophoresis samples of the Stieng community, we refound that hemoglobin varieties distributed as following: - HbE: 54.45% including HbE homozygous: 6.12%; HbAe: 41.5% and -thal/HbE: 6.8%.- -thal: only -thal/HbE (-thal/HbE: 4.08%, -thal/HbE, 2.72%). -Normal cases: 45.58%. These results shown that HbE ratio is very height in Stieng community, it is necessary to have the special investigations to find out the causes

We set out to analyse the result of 142 hyperthyroidsm patients, treated with radioiodine from 1987 to 1997, and still on follow-up by the Depar. of Nuclear medicine, Lam Dong General hospital. Among 142 patients studied, there are 123 females, 19 males. Their ages ranged from 19 to 65 years old (mean 35+/-9.8).

80 samples of street-food (40 samples of raw vegetable, 40 samples of cooked food) were examined at 4 places of crowed eating in Hue city. The infection of aerobic bacterium, total coliform, faecal coliform all were at very high concentration, highly-polluted level. 6 species of S.aureus and 3 species of NAG were isolated, 62.5% samples of cooked food and 100% samples of raw food were did not meet the sanitary standards, which leads to high risks of food poisoning due to infection
