A reduced retroversion angle of humeral head may predispose to recurrent anterior shoulder dislocation and may also be a factor in persistent instability after soft tissue procedures. Rotation osteotomy of proximal humerus is one of many surgical modalities proposed for recurrent anterior shoulder dislocation. To support such an operation, fundamental knowledge of shoulder anatomy is essential. The semi-axial view by Soderlund have been regarded as simple and reliable method for measuring humeral head retroversion angle. The purpose of this study was to evaluate validity of the semi-axial view and to assess reference values for humeral head retroversion angle in Korean. Humeral head retroversion angle was determined from 80 healthy subjects, 48 men and 32 women. Radiographs which shown less than 10degrees between humeral shaft axis and epicondylar axis were defined as acceptable radiographs by Soderlund. Acceptable radiographs were selected and two orthopedic surgeons measured retroversion angle, separately. Acceptable radiographs were obtained in only 70 shoulders (43.8%). The mean angle was 35.2+/-8.24degrees for dominant hand and 32+/-6.27degrees for nondominant in Korean. The mean angle was 35.3+/- 7.78degrees for right side and 31.9+/-6.8degrees for left. The interobserver difference was 2.9degrees. The semi-axial view by Soderlund was not reproducible solely. But if correct arm position is considered, the method presented is easy to use daily.

This study examined the characteristics of people who have preference for complementary medicine and also the psychosocial factors that are related to the selection of complementary medicine. Two-hunred subjects recruited from the community were included in this study. Demographic variables, medical service characteristics, health locus of control, social support, coping style, and personality charateritics such as self-esteem, neuroticism, and hypochondriasis were measured. It turned out that nearly 80% of the subjects had already experienced at least one alternative therapy in the past. However, past expeiece was not significant in predicting future complementary medicine usage. People who were older in age, had more information about complementary medicine, used active-behavioural coping styles, and had internal locus of control were more likely to use complementary medicine in the future. Recommenations for furthur research is indicated.

5.Sex-dependent liver cancer xenograft models for predicting clinical data in the evaluation of anticancer drugs
Laboratory Animal Research 2021;37(1):82-89
Background:
The incidence and mortality of liver cancer show a great difference between the sexes. We established sex-dependent liver cancer xenograft models and investigated whether such sex-dependent models could be used to simultaneously evaluate the therapeutic and adverse effects of anticancer drugs for drug screening.
Results:
In the in-vitro test, the cytotoxicity of anticancer drugs (cisplatin, 5-fluorouracil, and doxorubicin) was compared between male- and female-derived liver cancer cell lines. Cisplatin and 5-fluorouracil exhibited cytotoxicity without sex-difference, but doxorubicin showed dose-dependently significant cytotoxicity only in male-derived cells. Our results showed a strong correlation between preclinical and clinical data with the use of sex-dependent liver cancer xenograft models. Moreover, the male-derived Hep3B-derived xenograft model was more sensitive than the female-derived SNU-387-derived xenograft model against doxorubicin treatment. Doxorubicin showed more severe cardiotoxicity in the male xenograft model than in the female model. We investigated the occurrence frequency of doxorubicin-related cardiotoxicity using data obtained from the Korea Institute of Drug Safety & Risk Management Database, but no significant difference was observed between the sexes.
Conclusions
Our results suggest that sex-dependent xenograft models are useful tools for evaluating the therapeutic and adverse effects of anticancer drugs, because sex is an important consideration in drug development.

Von Hippel-Lindau disease (VHL) is a rare, autosomal dominantly transmitted familial, hereditary disease. This disease genetically predisposes affected people to the development of some types of tumor, such as cerebellar, spinal and medullary hemangioblastomas, and retinal angiomas, renal cell carcinomas and pheochromocytomas. Herein, a case of a cystic renal cell carcinoma, accompanied by Von Hippel-Lindau disease, treated by nephron sparing surgery, is reported. The VHL gene mutation of this case was also identified.

PURPOSE: Men with documented chronic prostatitis, with elevated serum prostate specific antigen (PSA), were investigated to assess whether treatment lowers serum PSA and thus avoids unnecessary biopsies. MATERIALS AND METHODS: The medical records of 46 men who presented with serum PSA higher than 4ng/ml, and subsequently diagnosed with chronic prostatitis, were retrospectively reviewed. After the administration of antibiotics and anti-inflammatory drugs for 4 to 8 weeks, the follow-up PSA levels were determined, and those with levels higher than 4ng/ml underwent a prostate biopsy. RESULTS: The mean PSA level decreased 61% from 11.66ng/ml before, to 3.79ng/ml after, treatment (p<0.001). In 30 patients the serum PSA level decreased to below 4ng/ml (mean 1.69), with these patients no longer having an indication for a prostate biopsy. In the remaining 16 patients the serum PSA level remained elevated above 4ng/ml, so they underwent a prostate biopsy. Pathological study revealed benign prostatic hyperplasia in 11 cases and prostate cancer in 5. The PSA level in patients associated with benign prostatic hyperplasia decreased 61.9% with treatment, from 19.96 to 7.88ng/ml (p=0.006) and the PSA in those associated with prostate cancer decreased 30.6% with treatment, from 12.85 to 7.32ng/ml (p<0.05). CONCLUSIONS: This study demonstrates that chronic prostatitis can cause elevation of serum PSA levels, and when identified, antibiotics and anti-inflammatory treatment can lower these levels and an unnecessary prostate biopsy can be avoided.

BACKGROUND: Left ventricular dilatation after acute myocardial infarction is caused by infarct expansion and compensatory dilatation of noninfarct area. This study was done to investigate the contributory topographical change of left ventricle to left ventricular dilatation after acute myocardial infarction. METHODS: 24 first acute myocardial infarction was studied with 2-dimensional echocardiography serielly. First study was done at 7days and second study was done 9 months after an infarction attack. Left ventricular volume was measured by Simpson's method in end-diastolic frame and change of end diastolic left ventricular surface area was measured in apical 4 chamber view. Left ventricular surface area was devided by ischemic(noncontraction) and nonischemic(contracting) area by connecting central point of long axis of left ventricle and the junction of dyssynergic motion and normal motion point in outer rim of left ventricle in end diastolic frame of apical 4 chamber view. RESULTS: Mean left ventricular end-diastolic volume at entry was 114+/-23ml and increased to 121+/-27ml at 9 months after acute myocardial infarction in whole group(p=0.02). In a subgroup of anterior infarction, the left ventricular surface area was increaed in 9 cases with increared left ventricular volume(34.8+/-5.1cm2 to 36.4+/-4.1cm2, p=0.02) and ischemic surface area did not change in these group. In 7 patients without increase in left ventricular volume, the left ventricular surface area did not change and ischemic surface area decreased(9.4+/-4cm2 to 8+/-3.2cm2, p=0.03) at 9 months. CONCLUSION: Thus the increase in left ventricular end-diastolic volume between 13 days and 9 months after acute myocardial infarction is considered to be a consequence of noninfarct ventricular area dilatation.

BACKGROUND: Celiprolol is a new generation beta-adrenoreceptor blocking agent with intrinsic sympathomimetic activity characterized by selective blockade of beta1 receptors and partial agonist activity at beta2 receptors. This study was designed to investigate the antihypertensive efficacy and safety of celiprolol in patients with essential hypertension. METHODS: The study subjects consisted of 36 patients(mean age : 55 years, 11 males, 25 females). Celiprolol was administered orally in a aily dose of 200-800mg once or two divided dose for 10 weeks after the admimstration of placebo for 2 weeks. RESULTS: Blood pressure was significantly reduced from 171+/-19/106.8mmHg to 153+/-20/92+/-12mmHg(p<0.01) after 2 week of therapy and this effect was maintained throughout the study periods. The efficacy rates were total 94%(marked improve : 53%, moderate improve : 22%, mild improve : 19%). The cumulative efficacy rate was 72% at 200mg/day, 91% at 400mg/day, and 94% at 800mg/day. Heart rate did not change throughout 10 weeks. There were no significant change in hematologic and blood chemistry variables. During the period of medication, headache developed in 3 cases(8%) and each of dry cough, dyspnea, epigastric pain and diarrhea and facial flushing developed in 1 case(2.8%) but they were tolerable. CONCLUSIONS: This results suggest that celiprolol is effective and safe drug in the treament of patients with essential hypertension.
