Ovarian leiomyoma is a rare form of the ovarian mesenchymal neoplasm and about 50 cases have been reported in the literature. It is believed that many cases may go unnoticed because they are usually small in size and frequently mistaken for the more common fibroma or fibrothecoma. Its origin is still controversial and many possibilities are considered including the smooth muscle in the blood vessel wall of the hilum or the multipotential ovarian stromal cell. Herein we describe two cases of ovarian leiomyoma with its characteristic histologic finding.

Aspirin(ASA) and NSAIDs can induce bronchoconstriction in 10~20% of adult asthmatics patients. Inhalation of lysine-ASA(L-ASA) has been described as an alternative method for diagnosis of ASA-sensitive asthma. To further understand the characterlstics of ASA-sensitive asthmas. we studied 38 asthmatic patients with ASA -sensitivity (36 intrinsic and 2 extrinsic asthma) proven by L-ASA bronchoprovocation test (BPT). Most were female (male to female ratio was 27:73). Twenty (53%) of them had no previous history of adverse reactions when exposed to ASA. Twenty nine (79%) had rhino-sinusitis symptoms. Early asthmatic response was observed in 16 (42%) patients, late only response in 16(42%), and dual response in 6(16%) patients. The threshold of L-ASA to provoke a positive response ranged from 11.2 to 180 mg/ml and most (68.3%) had a positive response after the inhalation of 180 mg/ml. Concurrent sensitivity to sulfite was noted in 14 (36%) patients, followed by sensitivity to tartrazine in one (3%) patient. None showed a positive response to sodium benzoate. After the avoidance from ASA/ NSAIDs with administration of anti-asthmatic medications, symptom and medication scores reduced in 26(87%) patients among 30 followed patients. They were classified into the improved group: four (13%) patients belonged to the not-improved group. There were no significant differences in clinical characteristics between the improved and not- improved group (p>0.05). In conclusion, L-ASA BPT could be considered as a useful method to diagnose ASA -sensitive asthma and be used to screen the causative agent for asthmatic patients with intrinsic type, especially in female patients with rhino-sinusitis and/or nasal polyp, even though they do not have arty history of adverse reactions. Cessation of exposure and proper treatment may allow to reduce symptom and medication scores.

Kaposi's sarcoma was first descrided by Kaposi in 1872 as an idiopathic multiple hemorrhagic sarcoma. Its clinical features revealed to be erythematous red or purple macule started out, and developing into palpable dome-shaped nodules. Etiology is not defined to detail at present. Kaposi's sarcoma is classified to 4 categories; Classical, African, Epidemic and Transplant type. Epidemic or AIDS categories is found approximately 20 % of all AIDS and has strong predilection for head and neck region. The first case of Kaposi's sarcoma observed in patients with kidney transplants was reported in 1969. Kaposi's sarcoma now accounts for 5% of all tumors associated with transplanted patients and alteration of the immunosuppression may have played a key role in these recipients. The most common site of Kaposi's sarcoma in transplanted patients are extremities but rare in head and neck area. We report a case of Kaposi's sarcoma on the hard palate in the kidney transplantation patient.

While intrathecal morphine in small doses has been effective in controlling postoperative pain, many patients have been suffered from the side effects. In recent studies, it has been suggested that small dose of propofol can attenuate these side effects of intrathecal morphine. We have studied the effect of propofol and tried to find the optimum dose that can reduce side effects of intrathecal morphine. Sixty patients of ASA class 1 scheduled for anorectal surgery were allocated randomly to receive either a bolus dose of propofol 0.5 mg/kg followed by an infusion of 1 mg/kg/24hr(group Pl) or 2 mg/kg/24hr(group P2) and no bolus dose followed by 1,000 ml 5% dextrose water(control group). In this study, postoperartive sedation, nausea, vomiting, pruritus and urinary retention were evaluated immediate postoperatively, 12 hour, 24 hour and 48 hour after spinal anesthesia using 1% tetracaine 5 mg with 10% dextrose water 5 ml and morphine 0.3 mg. As time passed, all the complications subsided significantly. However, there was no significant difference among 3 groups except pruritus. The incidence of pruritus was lower in the group P1 and group P2(80%, 50% respectively) than the control group(90%). In the 12 hour-after evaluation, there was no patient of grade 3 pruritus in the group P2 but 5 patients in the control group(p<0.001) and 3 patients in the group Pl had itching(p<0.05). The higher doses of propofol, the greater sedative effect observed. However, there was no clinicaliy serious problem (e.g. respiratory depression, deep sedation). In conclusion, we recommend that an adequate infusion dose of propofol for reducing the incidence and severity of pruritus is 2 mg/kg/24hr.

The taxonomy of Acanthamoeba spp., an amphizoic amoeba which causes granulomatous amoebic encephalitis and chronic amoebic keratitis, has been revised many times. The taxonomic validity of some species has yet to be assessed. In this paper, we analyzed the morphological characteristics, nuclear 18s rDNA and mitochondrial 16s rDNA sequences and the Mt DNA RFLP of the type strains of four Acanthamoeba species, which had been previously designated as A. divionensis, A. parasidionensis, A. mauritaniensis, and A. rhysodes. The four isolates revealed characteristic group II morphology. They exhibited 18S rDNA sequence differences of 0.2-1.1% with each other, but more than 2% difference from the other compared reference strains. Four isolates formed a different clade from that of A. castellanii Castellani and the other strains in morphological group II on the phylogenetic tree. In light of these results, A. paradivionensis, A. divionensis, and A. mauritaniensis should be regarded as synonyms for A. rhysodes.

The aim of this study was to determine whether losartan, an angiotensin II (Ang II) type 1 (AT1) receptor could influence the CA release from the isolated perfused model of the rat adrenal medulla. Losartan (5~50 micrometer) perfused into an adrenal vein for 90 min produced dose- and time-dependent inhibition of the CA secretory responses evoked by ACh (5.32 mM), high K+ (56 mM, a direct membrane depolarizer), DMPP (100 micrometer) and McN-A-343 (100 micrometer). Losartan failed to affect basal CA output. Furthermore, in adrenal glands loaded with losartan (15 micrometer) for 90 min, the CA secretory responses evoked by Bay-K-8644 (10 micrometer, an activator of L-type Ca2+ channels), cyclopiazonic acid (10 micrometer, an inhibitor of cytoplasmic Ca2+-ATPase), veratridine (100 micrometer, an activator of Na+ channels), and Ang II (100 nM) were markedly inhibited. However, at high concentrations (150~300 micrometer), losartan rather enhanced the CA secretion evoked by ACh. Collectively, these experimental results suggest that losartan at low concentrations inhibits the CA secretion evoked by cholinergic stimulation (both nicotininc and muscarinic receptors) as well as by membrane depolarization from the rat adrenal medulla, but at high concentration it rather inhibits ACh-evoked CA secretion. It seems that losartan has a dual action, acting as both agonist and antagonist to nicotinic receptors of the rat adrenal medulla, which might be dependent on the concentration. It is also thought that this inhibitory effect of losartan may be mediated by blocking the influx of both Na+ and Ca2+ into the rat adrenomedullary chromaffin cells as well as by inhibiting the Ca2+ release from the cytoplasmic calcium store, which is thought to be relevant to the AT1 receptor blockade, in addition to its enhancement of the CA release.

PURPOSE: The purpose of this study was to investigate the relationship between sexual knowledge, attitude, and satisfaction of sex education in university freshman. METHODS: The participants were 275 freshman students under the age of 20 years old. Data were collected in 2017 using a self-report questionnaire. RESULTS: The average scores of participants' sexual knowledge, attitude, and satisfaction of sex education were 24.22±4.94 out of 38 points, 90.81±15.86 out of 168 points, and 11.05±3.08 out of 20 points, respectively. With respect to the demographic characteristics, there were statically significant differences in sexual knowledge according to chances of relationship engagement (F=6.19, p=.002) and residence type (F=3.67, p=.013). Both sexual attitudes and satisfaction of sex education showed significant differences by major (t=3.20, p=.002; t=2.65, p=.009), types of high school (F=3.39, p=.019; F=3.53, p=.015), and interest in previous sex education during teenage years (F=2.88, p=.015; F=6.22, p<.001). Sexual knowledge showed a statistically significant correlation with attitudes (r=.153, p=.011). CONCLUSION: There is insufficient sex information available for college students. It is necessary in the future to develop sex education programs that are matched to college students' needs.

The two most common causes of acute arterial occlusion are embolism and thrombosis in sity. They are mainly originated from the cardiovascular sources. About 70-80 per cent of occlusions occur in the axial limb vessels. Therapeutic options include supportive measures, pharmacologic treatment, surgery, and non-operative interventions. There have been several successful case reports using percutaneous aspiration thromboembolectomy with the advent of new instruments and technical imprevement. We report a case of 70-year-old male with acute anterior wall myocardial infaction who experienced acute embolic arterial occlusion of the left popliteal artery from mural thrombus in the left ventricular apex. It wan managed successfully by percutaneous aspiration thromboembolectomy.

Xanthogranulomatous pyelonephritis is an atypical severe renal parenchymal infection, characterized macroscopically by a yellow lobulated mass, and microscopically by massive inflammatory cells and foamyhystiocytes. Preoperatively it can be confused with hypernephroma, pyonephrosis with stone or other renal inflammatory diseases, We present a case of xanthogranulomatous pyelonephritis associated with xanthogranulomatous epididymoorchitis. To our knowledge this is the first report of xanthogranulomatous pyelonephritis associated with xanthogranulomatous epididymo-orchitis.
