  • Cryptosporidium, a protozoan parasite, can cause cryptosporidiosis which is a gastrointestinal disease that can infect humans and livestock. Cattle are the most common livestock that can be infected with this protozoan. This study was carried out to determine the prevalence of Cryptosporidium infection in cattle in Kuantan, Pahang, Malaysia and to find out the association between the occurrence of infection and 3 different ages of cattle (calves less than 1 year, yearling, and adult cattle). The samples were processed by using formol-ether concentration technique and stained by modified Ziehl Neelsen. The results showed that 15.9% (24/151) of cattle were positive for Cryptosporidium oocysts. The occurrence of Cryptosporidium in calves less than 1 year was the highest with the percentage of 20.0% (11/55) followed by yearling and adult cattle, with the percentage occurrence of 15.6 % (7/45) and 11.8% (6/51), respectively. There was no significant association between the occurrence and age of cattle and presence of diarrhea. Good management practices and proper hygiene management must be taken in order to reduce the infection. It is highly important to control the infection since infected cattle may serve as potential reservoirs of the infection to other animals and humans, especially animal handlers.

  • This study was conducted in the saltwater crocodile (Crocodylus porosus) for the occurrence of various surgical affections with their clinical management. During the period of January 2006 to June 2008, a total of 68 adult crocodiles were considered as reference population from the Reptiles Farm Ltd. at Bhaluka, Mymensingh. The occurrence of surgical affections of adult female (88.9%) was significantly (P<0.01) higher than male (11.1%). Prevalence of common surgical affections were wound: 72.2%, fibroma: 11.1% abscess: 5.6%, fracture: 5.6%, tail necrosis: 2.8%, myiasis: 2.8%. Wound was the highest among the affections. Among the identified wounds, biting wound was higher. In summer (57.7%) the occurrence of wound was higher compared to other seasons. In winter season (7.7%) the occurrence of abscess, myiasis, fibroma were higher compared to other seasons. Wounds and fibroma are the major surgical affections in salt water crocodile. The most common site of surgical affection was recorded in crocodile's tail (30.6%). It was suggested that minimal stress, allowing constant and easy access to water, removal of roots of the tree in the basking land of crocodiles pen, basking land of the pen is better filling up by sand, clinical surgical managements are essential for better health and production.

  • PURPOSE: The present study evaluated the occurrence, somatometric, biochemical, and behavioral characteristics of young Korean sarcopenic males aged between 30 to 39 years. METHODS: The study involved a total of 1,546 participants. These individuals were divided into two distinct groups based on their skeletal muscle mass index. Of these, 49 participants were categorized into the sarcopenia group, while the remaining 1,497 individuals were placed in the normal group. The researchers analyzed the occurrence of sarcopenia, somatometric, biochemical, and behavioral characteristics such as height, weight, body mass index (BMI), waist circumference (WC), skeletal muscle mass index, fasting glucose (FG), triglyceride and total cholesterol (TC) levels, systolic (SBP) and diastolic blood pressure (DBP), and the drinking and smoking status. A complex sampling data analysis was performed. RESULTS: The weighted occurrence of sarcopenia was found to be 3.24%, (95% confidence interval (CI) of 2.39% to 4.36%). The somatometric contributing factors were height, BMI, and WC (p < .05). Triglyceride and TC levels exhibited statistically significant differences in the biochemical variables (p < .05). The behavioral characteristics, including the drinking and smoking status, had no statistical significance (p > .05). CONCLUSION: This study identified specific occurrences of sarcopenia and contributing factors in young Korean men.

  • Langerhans cell histiocytosis (LCH) is generally considered a childhood disease that exhibits various nonspecific clinical and radiological manifestations that mimic infection or malignancy. Here, we present a case of LCH involving the rib in an adult patient. CT and MRI revealed an expansile lytic lesion with periosteal reaction on the left 8th rib, suggesting a malignant bone tumor. Surgical resection was performed and histopathological examination was consistent with LCH. Owing to its rare occurrence in adults and nonspecific aggressive features, LCH should be included in the differential diagnosis of an aggressive-appearing rib lesion in both adults and children.

  • Epileptifrom discharges were induced in the telencephalon of the adult zebrafish via perfusion with pentylenetetrazole (PTZ), bicuculline methiodide, kainic acid-treated artificial cerebrospinal fluid (aCSF), and $Mg^{2+}$-free aCSF. Ginseng total saponin [GTS ($50{\mu}g/ml$)] was shown to attenuate the occurrence rate of epilpetiform discharges by 50-75%, compared to the control. Ginsenoside $Rg_1$ ($130{\mu}M$) reduced the epileptiform discharges in the isolated telencephalon and delayed the occurrence of behavioral seizures observed from the adult zebrafish placed in the PTZ (10 mM)-containing aquarium water. However, Re was not effective in the suppression of epileptiform discharges and behavioral seizures. These results indicate that $Rg_1$ may be useful in the control of epileptiform discharges and effective in controlling behavioral seizures, and that the zebrafish can be used as a model animal for the testing of potential anticonvulsant drugs.

  • In order to evaluate the effect of unilateral tooth clenching, the author observed a feature of producing the symptom complex related to pain and discomfort by the isometric unilateral canine biting under force of 5kg(FS) in Korean 31 adult females within normal masticatory function who were divided into the bilateral, the right and the left group according to their habitual sides of mastication, and analyzed the observed data statistically. The obtained results were as follows: 1. The duration of the isometric unilateral canine biting maintained before the occurrence of symptom complex related to pain and discomfort 66.72 seconds at right side and 39.50 seconds at left side in a group of subjects with bilateral habitual mastication. And the difference of the duration between of unilateral biting side was almost significant (P<0.05). 2. The most frequent region of occurrence of symptom complex related to pain and discomfort by the isometric unilateral canine biting was the contralateral superficial masseter muscle in a group of subjects with bilateral habitual mastication.

  • Purpose: This study was to identify factors predicting the occurrence of depression among patients with hepatitis C treated with Peg-interferon. Methods: The subjects were 134 patients treated with Peg-interferon after the diagnosis with hepatitis C at the D University Hospital and 3 hospitals located in Busan, South Korea. The predictors of depression were identified by measuring the general characteristics of the subjects and their disease-related characteristics, social support, sleep disorders, and degree of side effects by interferon. The data were analyzed with a t-test, ANOVA, and logistic regression using the SPSS/WIN 18.0 program. Results: Sixty-six point four percent of the subjects suffered from mild to more severe depression. Fatigue, hair loss, itching, and sleep disorders turned out to be significant predictors. In addition, the explanatory power of these variables for the occurrence of depression was 70%. Conclusion: Sleep disorders and drug side effects were determined to have significant influence on the development of depression in hepatitis C patients treated with Peg-interferon. Therefore, the development of nursing intervention programs aimed to prevent depression by effectively managing sleep disorders and side effects is mandated in future to help the given population.
