We evaluate the effects of diltiazem in 19 patients with ischemic heart disease (15 patients) of classical anginal pectoris & 4 patients of variant angina) by means of clinical status & electrocardiographic changes and obtain the results as follows: 1. The pulse rate & blood pressure were decreased by diltiazem slightly but these decreases were not significant in statistical meaning. 2. Diltiazem administration of 4 weeks duration normalized EKG completely in 4 patients & partially in 3 patients among the 13 patients who showed abnormal resting EKG initially. 3. All 19 patients who received diltiazem showed clinical improvement; 9 patients had excellent responses, 7 patients good responses & 3 patients fair responses. 4. Diltiazem had side effects in 3 patients, drowsiness, mild euphoria & possibly tolerance respectively in each patients.

PURPOSE: To evaluate the effect of Gd-DTPA on signal intensity of diffusion-weighted magnetic resonance (MR) image and apparent diffuse coefficient (ADC) in dog brain with hyperacute stroke. MATERIALS AND METHODS: Experimental canine model of hyperacute cerebral infarction was made by selective intraarterial embolization with particulate embolic material. Diffusion-weighted MR imaging was performed in five dogs at 1 hour after the embolization of internal carotid artery. After intravenous bolus injection of Gd-DTPA, additional 11 diffusion-weighted MR images were serially obtained from 2 minutes to 90 minutes after injection in each dog. The author evaluated findings of hyperacute cerebral infarction on diffusion-weighted MR imaging, and calculated mean signal intensity and mean ADC in infarcted region and contralateral normal region. Statistical analysis of mean signal intensity, mean ADC and contrast-noise ratio before and after Gd-DTPA injection was performed. RESULTS: Hyperacute cerebral infarction developed in all five dogs on diffusion-weighted MR images obtained 1 hour after embolization. The area of hyperacute infarction had steady increase in signal intensity on diffusion-weighted MR image and decrease in ADC. In normal perfusion area, decrease in signal intensity was observed at 2 minutes the Gd-DTPA injection, whereas ADC did not changed. CONCLUSION: Intravenous injection of Gd-DTPA had no influence on ADC in both hyperacute infarction and normally perfused area, but caused initial transient signal reduction in normally perfused area on diffusion-weighted MR image due to susceptibility effect of Gd-DTPA. It is important to calculate ADC in evaluating the effect of diffusion after injection of Gd-DTPA.

PURPOSE: To evaluate the clinical features of high myopic eyes with cataracts implanted with negative power intraocular lenses (IOLs) at the time of cataract surgery. METHODS: A retrospective chart review was conducted of 18 eyes of 14 patients who underwent cataract surgery with negative power IOLs and 10 eyes in 9 patients with low power IOLs. We investigated axial length, IOL power, preoperative and postoperative best-corrected visual acuity (BCVA) and preoperative and postoperative spherical equivalent (SE) refractive errors. RESULTS: Mean BCVA showed significant improvement in both groups. We measured postoperative SE refraction and the difference between the mean intended and the mean achieved SE refractive errors in the negative power group (17 eyes) was +1.59 ± 1.34 D and +0.31 ± 0.50 D in the low power group. CONCLUSIONS: BCVA was significantly improved in the majority of eyes, although they had myopic macular degeneration or posterior staphyloma. However, the mean achieved postoperative SE refraction was more hyperopic than the predicted postoperative SE error. Additionally, hyperopic refractive error was greater in the negative power group than the low power group. Therefore, we recommend that postoperative hyperopic refractive error should be considered when performing cataract surgery in high myopic patients.

A series of 119 Mycobacterium avium complex isolates were subjected to clarithromycin susceptibility testing using microplates containing 2,3-diphenyl-5-thienyl-(2)-tetrazolium chloride (STC). Among 119 isolates, 114 (95.8%) were susceptible to clarithromycin and 5 were resistant according to the new and the standard method. STC counts the low cost and reduces the number of procedures needed for susceptibility testing.

BACKGROUND: Since better understanding of the associations between blood pressure and blood lipids may provide insight into the mechanisms by which hypertension is associated with increased risk of coronary heart disease, this study is aimed to explore the associations of blood pressure with serum lipids, BMI, age, FBS and life style factors. METHODS AND RESULTS: In this study, 20,826 men and 10,209 women were included for the assessment of the cross-sectional relations of blood lipids, BMI, Blood pressure and Life style factors. Stratified analyses and multivariable methods were used to control for potential confounding anthropometric and lifestyle variables. Total cholesterol and Triglyceride levels increased significantly with increasing systolic or diastolic blood pressure in both sexes. Men of 20-29 years old had steeper regression slopes for blood pressure by total cholesterol level than did women of similar age. In men, the association between blood pressure and total cholesterol level decreased with age, whereas in women, no change was observed regarding age. Body mass index modified the relation, whereas smoking, exercise, and alcohol consumption had little influence on the association. HDL cholesterol level had little influence on blood pressure. In the group of age <40, age accounted more than BMI for hypertension, whereas in group of age > or =40, BMI accounted more. In the group of age < 40, other variables ,besides age and BMI, are suggested to influence more on male hypertension than female hypertension. CONCLUSION: These results provides evidence that there are interrelations between blood pressure, blood lipids and life style factors that may influence the mechanisms of coronary heart disease.

An abnormal course of carotid artery may surprise surgeons during surgery and result in an transient ischemic attack or other ischemic symptoms. We report an unusual case of kinking in the common carotid artery located below the right thyroid lobe, which was found during a total thyroidectomy in a 74-years old patient. We emphasize in this case how important it is to palpate the neck before surgeries such as tracheostomy, thyroid surgery and so on.
