It is evident that an elevation of airway albumin excreation rate without clinical proteinuria strongly predicts a later progression on diabetic renal disease. So we studied the correlation between Microalbumin checkly RIA & Micral-Test®. We collected urine between 08:00 h and 08:00 h next day and then checked microalbuminuria by radioimmunoassay method and Micral-Test® The results are as follows: 1. There was significant correlation between microalbuminuria checked by RIA & Micral-Test® 2. There was poor correlation between diabetes duration or HV-A1c and maximal change in albumin excreation rate. 3. So we concluded that Micral-Test® can be used in laboratory instead of RIA.

Foveal hypoplasia has been described in association with aniridia, albinism, microphthalmia and achromatopsia. Isolated foveal hypoplasia unassociated with other ocular abnormalities has been rarely reported and is regarded as a rare condition. Authors experienced two cases of isolated foveal hypoplasia in the same family. A 30-year-old woman and her 3-year-old daughter presented with a complaint of poor visual acuity and nystagmus. Ophthalmoscopic examination of their both eyes revealed loss of foveal reflex, absence of macular luteal pigment, and abnormal distribution of retinal vessels at the posterior pole. No abnormal ocular findings other than lens opacity, high myopia, and large optic cup were found.

3.Withaferin-A Inhibits Colon Cancer Cell Growth by Blocking STAT3 Transcriptional Activity.
Journal of Cancer Prevention 2015;20(3):185-192
BACKGROUND: Withania somnifera (known as Ashwagandha) is a medicinal plant used in the ayurvedic medicines in India. Withaferin-A, a withanolide derived from the leaf extract of W. somnifera, has been reported to exhibit anti-tumor activity against various cancer cells, such as leukemia, breast cancer and colon cancer cells. METHODS: We investigated the anti-cancer effects of withaferin-A on the proliferation and migration of human colorectal cancer (HCT116) cells. And we evaluated the effects of withaferin-A on the transcriptional activity of STAT3 and the growth of HCT116 cells in xenograft mouse tumor model. RESULTS: In the present study, we found that withaferin-A inhibited the proliferation and migration of HCT116 cells in a concentration-dependent manner. Treatment of HCT116 cells with withaferin-A attenuated interleukin-6-induced activation of STAT3, which has been implicated in the development and progression of colon cancer. To examine the effect of withaferin-A on HCT116 cells proliferation in vivo, we generated HCT116 cells xenograft tumors in Balb/c nude mice and treated the tumor bearing mice with or without withaferin-A intraperitoneally. Treatment with withaferin-A exhibited significant decrease in the volume and weight of tumors as compared to untreated controls. CONCLUSIONS: The present study suggests that withaferin-A holds the potential to be developed as a small molecule inhibitor of STAT3 for the treatment of HCT116.

PURPOSE: Bilateral high signal intensity in basal ganglia on Tl-weighted images is unusual. the purpose of this study is to describe the pattern of high signal intensity and underlying disease. METHODS AND MATERIALS: During the last three years, 8 patients showed bilateral high signal intensity in basal ganglia on Tl-weighted image, as compared with cerebral white matter. Authors analized the images and underlying causes retrospectively. Of 8 patients, 5 were male and 3 were female. The age ranged from 15 days to 79 years. All patient were examined by a 0.5T superconductive MRI. Images were obtained by spin echo multislice technique. RESULTS: Underlying causes were 4 cases of hepatopathy, 2 cases of calcium metabolism disorder, and one case each of neurofibromatosis and hypoxic brain injury. These process were bilateral in all cases and usually symmetric. In all cases the hyperintense areas were generally homogenous without mass effect or edema, although somewhat nodular appearence was seen in neurofibromatosis. Lesions were located in the globus pallidus and internal capsule in hepatopathy and neurofibromatosis, head of the caudate nucleus in disorder of calcum metabolism, and the globus pallidus in hypoxic brain injury. CONCLUSION: Although this study is limited by its patient population, bilateral hyperintense basal ganglia is associated with various disease entities. On analysis of hyperintense basal ganglia lesion, the knowledge of clinical information improved diagnostic accuracy.

Recently, several reports of extrahepatic hepatocellular carcinoma metastasis demonstrated by technetium-99mTc-IDAs scan have shown that 99mTc-IDAs can be used to detect extrahepatic metastasis in hepatocellular carcinoma. We report here a case of hepatocellular carcinoma with pulmonary nodules that were demonstrated as metastasis in nature by the use of the 99mTc-DISIDA. The findings in this case and several reports reviewed here suggest that the 99mTc-DISIDA scan may be a useful diagnostic agent that can detect the extrahepatic metastasis of hepatocellular carcinoma and stage the disease. But more clinical study in needed to establish the position of 99mTc-DISIDA in the field of diagnosis of extrahepatic hepatocellular carcinoma.

To evaluate the features of pyuria related to the bacteriuria, 140subjects were studied from Jan. 1987 to Dec. 1987. They pyuria was frequently developed from the age 30 to 60 years old, and male to female ratio was 1:1.41. The most common disease was urethrocystitis that was shown 42.8%. Common precipitating factors were urethral catheterization (25%) and urinary tract obstruction (11.4%). Through the observation, symptomatic pyuric patients were 66 subjects (47.1%), and the subjects with significant urine culture were 121 subjects (86.4%). In the urine culture, the most common bacteria was E. coli (41.4%), and the next was Pseudomonas (19.3%). A large percentage of E. coli and Pseudomonas was susceptible of amikin. The pyuria due to S. epidermidis and Accinatobacter was well treated. High therapeutic rate was observed in the acute pyelonephritis (71%) and urethrocystitis (67%). In the persistent urinary tract infection, there were relapsing (22 cases) and recurrent urinary tract infection (16 cases).

Two cases of acute digitalis poisoning were presented. The first patient was 20-year-old male with asymptomatic ventricular septal defect (maladie de Roger) who attempted suicide by ingestion of degitalis leaf about 6.0 g (60 tablets). He developed severe epigastric pain and vomiting one hour after ingestion. Syncopal attack was developed once for a few minutes and recovered. Electrocardiogram revealed 2:1 A-V block. By conservative management he was recovered. The second patient was 2-year-old, healthy baby who ingested digoxin about 2.5 mg(10 tablets) by accident. He developed severe vomiting and electrocardiogram revealed 1degrees, 2degreesand 3degrees A-V block in series. He was recovered by conservative management without sequele.

To assess the role of multiple factors in influencing occurrence of ventricular premature complexes after acute myocardial infarction twenty-four hour Holter electrocardiographic tape recording were made in 40 survivors of an acute myocardial infarction 10 to 20days after attack. Ventricular premature complexes in the early post infarction period were not correlated with left ventricular function, age, sex, smoking, diabetes mellitus, previous angina, and previous myocardial infarction. The occurrence of ventricular premature complexes showed a positive correlation with the occurrence of ST-T change. The occurrence of ventricular premature complexes during sleep hours was compared to the awake state. In 22 patients, the incidence of ventricular premature complexes are excluded from analysis, the 22 of patients, or in 76 percent, sleep was associated with a lowered occurrence of ventricular extrasystoles.

Journal of the Korean Ophthalmological Society 1975;16(3):198-200
The effect of 1% atropine solution and 1% atropine ointment on healing of corneal epithelium in 20 rabbits was studied. Corneal epithelium was removed by #15 blade in central area of 7mm in diameter under topical anesthesia with 0.5% pontocaine. 1% atropine solution was applied three times daily to Rt. eyes, and 1% atropine ointment to Lt. eyes. Progress of epithelial healing was observed by fluorescent staining of the wound. At the end of 24 hours, fluorescent staining area was 46.90% in average for Rt. eyes, and 51.90% in average for Lt. eyes. At the end of 48 hours, it was 7.83% for Rt. eyes, and 11.0% for Lt. eyes. At the end of 72 hours, All of Rt. eyes did not stain, but 2 of 10 Lt. eyes were faintly stained. Difference between ophthalmic solution and ointment on the effect of corneal epithelial healing was not significant.
