Zika virus (ZIKV) was first isolated in Asia from mosquitoes from Malaysia in 1966. However, the incidence of Zika and Zika-related neurological complications in Asia is not well known. The few studies of Zika in Asia have been inconsistent in pointing to likely transmission levels, with some studies suggesting substantial transmission and others not. Interpretation of existing epidemiological and public health data from Asia is constrained by the non-specific symptomatology of Zika, the high proportion of subclinical ZIKV infections, relatively low viremia, and the lack of accurate serological assays. Here, we update the status of Zika cases from countries in Asia, and highlight some key knowledge gaps. In particular, accurate determinations of the incidence of Zika-related congenital Zika syndrome should be a priority for Zika research in Asia. Additional information will be critical to make informed strategies for the prevention and control of this global public health threat.

This study is an attempt to investigate the effect of total Ginseng saponin (GTS) on the blood pressure of the rat and to elucidate its mechanism of action. GTS, when injeced into a femoral vein of the rat, caused dose-related fall in blood pressure with secondarily elevation of the blood pressure. The depressor effect of GTS was blocked by treatment of atropine and prazosin, but not affected by pretreatment with chlorisondamine or cyproheptadine. GTS inhibited significantly the pressor response evoked by norepinephrine. The pressor effect of GTS was not affected by treatment with atropine or cyproheptadine, but was attenuated markedly by pretreatment with chlorisondamine. From the above mentioned results, it is thought that GTS produces the pressor and the depressor actions in the rat, and that its depressor response is exerted partly through the stimulation of cholinergic muscaric receptors with the blockade of adrenergic alpha-receptors, and that its pressor response is revealed by stimulation of nicotinic receptors in autonomic ganglia.

Travel-acquired dengue cases have been increasing as the overall global dengue burden has expanded. In Korea, imported dengue cases have been reported since 2000 when it first became a notifiable disease. During the first four months of 2016, three times more dengue cases were reported in Korea than during the same period the previous year. A safe and efficacious vaccine for travelers would be beneficial to prevent dengue disease in individual travelers and potentially decrease the risk of virus spread to non-endemic areas. Here, we summarize the characteristics of dengue vaccines for travelers and review dengue vaccines currently licensed or in clinical development.

BACKGROUND: Pravastatin, HMG-CoA reductase inhibitor, has been known to be the most effective drug in patients with hypercholesterolemia. We studied the effectiveness and side effects of this drug. METHODS: We studied twenty four patients(8 males, 16 females), with pravastatin 5mg bid for 8 weeks, whose fasting serum total cholesterol levels were higher than 240mg/dl on the first visit. Lipid profiles were checked at 2 weeks interval for 8 weeks and compared with baseline level individually. RESULTS: Among lipid profiles, pravastatin significantly decreased the total cholesterol from 282.8mg/dL to 224.5mg/dL(reduction rate, 21%), the LDL cholesterol from 197.2mg/dL to 143.8mg/dL(27%), the total cholesterol/HDL cholesterol ratio from 6.2 to 4.6(25%), and the LDL cholesterol/HDL cholesterol ratio from 4.1 to 2.7 (34%). These changes were statistically significant(p<0.05). Triglyceride and HDL cholesterol showed no significant changes compared to baseline levels during treatment. The clinical and laboratory findings after treatment did not show serious abnormalities except two patients who dropped out due to side effect such as constipation and skin eruption. CONCLUSION: Results from the present study show that short-term pravastatin therapy seems to be effective and safe in patients with hypercholesterolemia.

This study evaluated the epizootiological characteristics of equine coital exanthema (ECE) in South Korea. A PCR test was used to determine the equine herpesvirus 3 (EHV-3) release period, excretion by suckling foals, morbidity rate, effect on fertility, and onset of breeding partner after treatment. The morbidity rate of ECE based on clinical symptoms was 8.3% (2/24) for stallions and 10.8% (45/416) for mares, and 29 of 45 (64.4%) animals were positive on the PCR test. Ten (22%) broodmares had symptoms before breeding, while 26 (58%) had symptoms after breeding. Nine (20%) mares had uncertain coverage periods and occurrence times. Suckling foals had no clinical findings and EHV-3 was not detected in their nostrils, although it was detected on teasers. No lesions were observed in the clitoral fossa on broodmares, although EHV-3 was detected by PCR. The period of EHV-3 emission was 22~23, 18~19, 6, and 58 days in stallions, broodmares, teasers, and mares with a mixed E. coli-like infection, respectively. ECE had no negative effects on the breeding capability of stallions and no symptoms were observed in broodmares after recovering from ECE.

The racehorses that under arthroscopic surgery due to be injured his limbs were studied during exercise or training at Busan Race Park from 2005 to 2010. Rate of arthroscopic surgical treatments was 1.4% (63/4,642). Affected bones were radius, radial carpal bone, third carpal bone, proximal phalanx, third metacarpal bone, femur, tibia, proximal sesamoid bone and intermediate carpal bone. The lesions were fracture, chip fracture, slap fracture, osteochonrosis, and osteochondrotitis dissencans. Number of patients under arthroscopic surgery were 63. Success horses of returned to racetrack or tried to return to racetrack were 58, and 5 horses were in training or resting at the time of publication. Success horses of returned to their previous use in the patients were 49 horses (84.4%) and no returned to the racetrack were 9 horses (15.6%) in 58 horses.

Epidermal growth factor receptor (EGFR) is overexpressed in various malignancies including carcinoma of the breast, lung, esophagus, cervix, and stomach. In patients with cervical carcinoma, its overexpression may be associated with advanced stage and poor prognosis. So, we evaluated the levels of serum EGFR in patients with cervical carcinoma. The level of EGFR extracellular domain was determined in serum from 57 cervical carcinoma patients(adenocarcinoma: 2, squamous cell carcinoma: 39, carcinoma in situ(CIS): 16) and 28 cases of healthy control using enzyme-linked immunosorbent assay(Calbiochem). In invasive carcinoma, serum EGFR level was measured in 11 cases of Stage Ia, 9 cases of Stage Ib, 4 cases of Stage IIa, 15 cases of Stage IIb, 2 cases of stage III patients. The mean ages of the healthy controls, of the wome with carcinoma in situ(CIS), and with invasive cervical carcinoma were not different(49.3, 44,4, 49.5, respectively, p 0.241). The mean serum level of EGFR in healthy control(n 28), carcinoma in situ(CIS)(n 16), and invasive carcinoma patients(n=41) were not significantly different(71.4+/-12.8fmol/ml, 79.2+/-26.8fmol/ml, 61.8+/- 18.4 fmol/ml, respectively, p=0.071). In conclusion, the expression of EGFR was not increased in patients with cervical cancer compared with normal women. And no significant differences were found depending on the clinical stage.

The object of this study was to evaluate recurrence of equine coital exanthema (ECE) whether re-infection or re-activation of causative virus. ECE is a venereal disease of horses caused by equine herpesvirus type 3 (EHV-3). Like other herpesviruses, it may persist in infected horses for a long time. There is a controversy on the cause of ECE as the recurrence or the reinfection. This disease had occurred firstly on stallions and broodmares in Korea. The horses had rebreeded after healing routinely. Next year, the disease recurrented on the just same affected horses among stallions. The result of this study, re-outbreak of ECE in stallions is recurrence of ECE, but not reinfection of the virus.
