  • Rheumatoid arthritis is a chronic, systemic, and inflammatory autoimmune disorder that affects 1% of the adult population worldwide. Osteoarthritis is a multifactorial disease with high morbidity that is characterized by degradation of the matrix and destruction of articular cartilage. In this study, we examined the inhibition effect of Trachelospermi Caulis on the inflammation($TNF-{\alpha}$, $IL-1{\beta}$, NO), cartilage protection(MMP-13), and cell death in arthritis. RAW 264.7 and SW 1353 cells were cultivated in DMAE(GibcoBRL, USA) with 5% FBS and Fungizone in $37^{\circ}C$, 5% CO2. THP-1 cells were cultivated in RPMI(GibcoBRL, USA) with 5% FBS and Fungizone in $37^{\circ}C$, 5% CO2. Activity of caspase-3, XIAP, Cytochrome C in the cell was examined by using western blot. The results obtained were as Follows; Concentration of nitric oxide in Trachelospermi Caulis treatment group significantly decreased compared with that of non-treatment group (P<0.05). In treated group, Concentration of Trachelospermi Caulis was not significantly associated with cell death. Concentration of $TNF-{\alpha}$ and $IL-1{\beta}$ in Trachelospermi Caulis treatment group decreased significantly compared with that of none treatment group (P<0.05). Relative density of MMP-13 in Trachelospermi Caulis treatment group decreased significantly compared with that of none treatment group and dose-response relationship was observed. After treatment of staurosporin in SW1353 which increases cell death, in Trachelospermi Caulis treated group, the cell death was effectively decreased. In conclusion, these results suggest that Trachelospermi Caulis inhibit inflammation and cell death in arthritis. More researches about effect of Trachelospermi Caulis are considered to need.

  • Gastric ulcer has multifactorial etiology, and the development of ulcer is known to be caused by gastric acidity, pepsin secretion, gastric motility and gastric mucosal blood flow. The ulcer results from the tissue necrosis and apoptotic cell death triggered by mucosal ischemia, free radical formation and cessation of nutrient delivery. The gastric mucosa is usually exposed to a wide range of aggressive insults, and has developed efficient mechanisms to repair tissue injury. The apoptotic process of gastric mucosa is triggered by the induction of such proapoptotic gene expression, such as BAX. The Bcl-2 family of proteins plays a pivotal role in the regulation of apoptosis. The maintenance of gastric mucosa integrity depends upon the ratio between cell proliferation and cell death. Stress-inducing factors may affect Bcl-2/BAX ratio and thus the rate of apoptosis through modulation of the expression of both proteins depends upon the experimental model. In addition to the regulation of apoptosis, new vessels have to be generated in order to ensure an adequate supply of oxygen and nutrients to the healing gastric mucosa. This events are regulated by several factors. Among them, such polypeptide growth factors, such as vascular endothelial growth factor (VEGF) regulates essential cell functions involved in tissue healing including cell proliferation and differentiation. The purpose of this study was carried to investigate whether Rhei Rhizoma administration might protect apoptotic cell death and promote angiogenesis in gastric mucosa. Sprague-Dawley rats were randomly divided into 4 groups; normal, saline, cimetidine and Rhei Rhizoma-treated group. The saline, cimetidine and Rhei Rhizoma extracts were orally administrated to each group and gastric ulcer was induced by HCl-EtOH solution. After 1 hour, the stomachs were collected for histological observation and immunohistochemistry. In results, Rhei Rhizoma proves to promote to heal wound in gastric ulcer in conclusion and the significant changes of BAX, Bcl-2 and VEGF quantity in gastric mucosa were observed. These results suggest that Rhei Rhizoma extract may promote incision wound healing and has protective effects on gastric ulcer in rats.

  • As with humans, overweight or obesity is a major health concern in the companion animal population. A cross-sectional questionnaire-based survey of dog owners attending primary small animal veterinary practices from different areas in Chuncheon, Kangwon province, Korea was undertaken to explore the relationships between socioeconomic and other relevant risk factors associated with canine obesity. In addition, the author was to estimate the prevalence of obesity compared to published literatures for dogs. Owners were asked about dog age, neuter status, feeding habits, dog exercise, household income and owner age. The body condition score (BCS) of the dogs was also assessed. Multivariable binary logistic regression was used to assess the association between BCS and potential risk factors controlling for confounding variables, using odds ratios (OR), 95% confidence intervals (CIs). A total of 275 dogs (136 males and 139 females) aged 1-12 years (mean age $5.6{\pm}3.7$ years) were surveyed in 2013. Of these, 46.9% of dogs (n = 129) were classed as an ideal body shape (BCS = 3), 30.9% (n = 85) were overweight (BCS = 4), 8.4% (n = 23) were obese (BCS = 5) and 13.8% (n = 38) were underweight (BCS = 1 or 2). Neutered males and spayed females had the highest prevalence of obesity (43.4% and 33.9%); intact females had the lowest prevalence of obesity (31.6%). In univariable model, risk factors associated with canine obesity are multifactorial and include owner income, owner age, age of dog, neuter status, frequency of feeding per day, frequency of snacks and consultation with veterinarian on dog's weight. In final multivariable logistic regression model, dogs whose owners reported no consultation with veterinarians for weight management were significantly more likely to be obesity than ideal (OR = 7.6, 95% CI, 4.2-13.8; p < 0.0001). This study showed a high prevalence of obesity in domestic companion dogs. Since this was a cross-sectional study with small samples, the association of canine obesity with risk factors warrants more research. To the author's best knowledge, this is the first Korean study on dog body condition and obesity.

  • Bedwetting is the most common urologic complaint among children. Wetting frequency decreases from birth to adolescence. Etiology is multifactorial : genetic, neuromuscular or urologic maturation, psychosocial stressors, toilet training, or biologic aspects. Treatment has been also multimodal : drugs to depress bladder activity, increase urethral resistance, or modulate sleep. and recently urine reduction modulation. All of these approaches reflect a lack of sufficient knowledge of the underlying pathophysiology of nocturnal enuresis. Recent researches have focused on sleep disturbances, bladder reservoir function, urine output, and a combination of the three. Sleep studies indicate that enuretic patients are normal sleepers, and enuresis can take place during any stage of sleep, but generally occurs when the bladder is filled to the equivalent of maximal daytime functional capacity. Bladder reservior capacity appears to be normal, and bladder instability is somewhat related with the pathology of nocturnal enuresis. However, enuretic patients have shown the lack of normal nocturnal increase in antidiuretic hormone levels, and nocturnal urine production increases up to 2-4 times volume of functional bladder capacity, which explains the need for bladder emptying. But behavioral approaches, especially Bell-alarm method, remain important in the treatment of primary enuresis.

  • Craniopharyngiomas are rare primary intracranial tumors. Despite their benign histological appearance, they are often associated with an unfavorable prognosis. The typical manifestations upon diagnosis are headache, visual impairment, polyuria/polydypsia, growth retardation, disturbance of pubertal development, and significant weight gain. The treatment options include radical surgery or radiotherapy, or a combination of these modalities. Slipped capital femoral epiphysis (SCFE) is the most common adolescent hip disorder. SCFE occurs when the capital femoral epiphysis displaces posteriorly on the femoral neck at the level of the physis. The etiology of SCFE is thought to be multifactorial and may include obesity, growth surges, and less common endocrine disorders. The related endocrine disorders include hypothyroidism, growth hormone supplementation, hypogonadism, and panhypopituitarism. Reported herein is a case of panhypopituitarism caused by craniopharyngioma combined with SCFE.

  • Introduction: Upper aero-digestive tract cancer is a multidimensional problem, international trends showing complex rises and falls in incidence and mortality across the globe, with variation across different cultural and socio-economic groups. This paper seeks some explanations and identifies some research and policy needs. Methodological Approach: The literature illustrates the multifactorial nature of carcinogenesis. At the cellular level, it is viewed as a multistep process involving multiple mutations and selection for cells with progressively increasing capacity for proliferation, survival, invasion, and metastasis. Established and emerging risk factors, in addition to changes in incidence and prevalence of cancers of the upper aero-digestive tract, were identified. Risk Factors: Exposure to tobacco and alcohol, as well as diets inadequate in fresh fruits and vegetables, remain the major risk factors, with persistent infection by particular so-called "high risk" genotypes of human papillomavirus increasingly recognised as also playing an important role in a subset of cases, particularly for the oropharynx. Chronic trauma to oral mucosa from poor restorations and prostheses, in addition to poor oral hygiene with a consequent heavy microbial load in the mouth, are also emerging as significant risk factors. Conclusions: Understanding and quantifying the impact of individual risk factors for these cancers is vital for health decision-making, planning and prevention. National policies and programmes should be designed and implemented to control exposure to environmental risks, by legislation if necessary, and to raise awareness so that people are provided with the information and support they need to adopt healthy lifestyles.

  • Lung cancer is one of the most common malignancies in the world. Its incidence and mortality rates are on the rise in Pakistan. However, epidemiological studies to identify common lung cancer determinants in the Pakistani population have been limited. In this study, data of 440 cases and 323 controls were collected from different hospitals in Peshawar and Islamabad, along with information about socio-demographic factors including age, sex and smoking. Univariate and multi-factorial analyses of socio-demographic factors in association with each other were also performed. Overall survival analysis highlighted that, out of 440 patients in the lung cancer dataset, 204 people were uncensored with a median survival time of 13 months (95% CI=12-18). There were 41 femaleand 399 male patients. Differences were observed between length of survival in the males and females (${\chi}12$ = 6.1; p-value = 0.01). Gender was observed to be significantly related to survival (p-value< 0.01), with better survival in females (hazard ratio=2). Cox regression was extended to adjust for the covariate age (z = 2.5; p-value = 0.02). Survival analysis was also performed on the basis of smoking groups (current smokers, former smokers and never smoked individuals) and smoking duration (smoking duration >10 years, <10 years and never smoked). Smoking duration was significantly associated with survival (p-value < 0.01), with better survival in never smokers in comparison to both smoking for greater or less than 10 years. Strong associations were observed for smoking group with duration greater than 10 years, OR=6.1(3.9-9.5) on univariate and multifactorial analysis OR=11.3(CI=6.8-19.3).

  • The nonsyndromic cleft lip and palate (NSCL/P) is a congenital deformity of multifactorial origin with a relatively high incidence in the oriental population. Various etiologic candidate genes have been reported with conflicting results, according to race and analysis methods. Recently, the ablation of the TGF-${\beta}3$ gene function induced cleft palates in experimental animals. Also, polymorphisms in the TGF-${\beta}3$ gene have been studied in different races; however, they have not been studied in Koreans. A novel A $\rightarrow$ G single nucleotide polymorphism (defined by the endonuclease SfaN1) was identified in intron 5 of TGF-${\beta}3$ (IVS5+104 A > G). It resulted in different genotypes, AA, AG, and GG. The objective of this study was to investigate the relationship between the SfaN1 polymorphism in TGF-${\beta}3$ and the risk of NSCL/P in the Korean population. The population of this study consisted of 28 NSCL/P patients and 41 healthy controls. The distribution of the SfaN1 genotypes was different between the cases and controls. The frequency of the G allele was significantly associated with the increased risk of NSCL/P [odds ratio (OR) = 15.92, 95% confidence interval (CI) = 6.3-41.0]. The risk for the disease increased as the G allele numbers increased (GA genotype: OR = 2.11, 95% CI = 0.38-11.68; GG genotype: OR = 110.2, 95% CI = 10.67 - 2783.29) in NSCL/P. A stratified study in patients revealed that the SfaN1 site IVS5+104A > G substitution was strongly associated with an increased risk of NSCL/P in males (p < 0.001), but not in females. In conclusion, the polymorphism of the SfaN1 site in TGF-${\beta}3$ was significantly different between the NSCL/P patients and the control. This may be a good screening marker for NSCL/P patients among Koreans.

  • Background: Initiation, perpetuation and cessation of smoking are all multifactorial. It is essential to explore interactions among various parameters influencing smoking and its cessation for effective smoking cessation interventions. Objectives: To obtain insights into smoking and its cessation among current smokers in India. Materials and Methods: The present study was conducted among current smokers visiting the Department of Oral Medicine and Radiology, Manipal College of Dental Sciences (MCODS), Manipal University, Mangalore. Knowledge, attitudes, behavior, worksite practices towards smoking and its cessation, barriers to smoking cessation and socio-demographic variables were explored using a structured, pretested, self-administered questionnaire. Results: A total of 175 current smokers participated in the study. Mean knowledge, attitude, worksite practice and barrier scores were $15.2{\pm}5.67$ (66.1%), $57.5{\pm}7.67$ (82.1%), $4.18{\pm}2.02$ (41.8%) and $57.4{\pm}12.37$ (63.7%) respectively. Correlation analysis revealed: association of knowledge with education, occupation and religion; attitude with education and occupation; worksite practices with occupation; knowledge with attitude; and barriers negatively with worksite practices. The majority (85.7%) of respondents intended to quit smoking and this was associated with higher attitude scores, whereas actual quit attempts were associated with high knowledge, attitudes, worksite practices and low barrier scores. Conclusions: Various socio-demographic factors associated with smoking and its cessation were identified. The present study highlights the importance of identifying and targeting these interactions while framing guidelines and interventions for effective tobacco cessation in a developing country like India.

  • Objective : We conducted a retrospective study examining the outcomes of intracerebral hemorrhage (ICH) in patients with chronic kidney disease (CKD) to identify parameters associated with prognosis. Methods : From January 2001 to June 2008, we treated 32 ICH patients (21 men, 11 women; mean age, 62 years) with CKD. We surveyed patients age, sex, underlying disease, neurological status using Glasgow Coma Scale (GCS), ICH volume, hematoma location, accompanying intraventricular hemorrhage, anti-platelet agents, initial and 3rd day systolic blood pressure (SBP), clinical outcome using the modified Rankin Scale (mRS) and complications. The severity of renal functions was categorized using a modified glomerular filtration rate (mGFR). Multifactorial effects were identified by regression analysis. Results : The mean GCS score on admission was $9.4{\pm}4.4$ and the mean mRS was $4.3{\pm}1.8$. The overall clinical outcomes showed a significant relationship on initial neurological status, hematoma volume, and mGFR. Also, the outcomes of patients with a severe renal dysfunction were significantly different from those with mild/moderate renal dysfunction (p<0.05). Particularly, initial hematoma volume and sBP on the 3rd day after ICH onset were related with mortality (p<0.05). However, the other factors showed no correlation with clinical outcome. Conclusion : Neurological outcome was based on initial neurological status, renal function and the volume of the hematoma. In addition, hematoma volume and uncontrolled blood pressure were significantly related to mortality. Hence, the severity of renal function, initial neurological status, hematoma volume, and uncontrolled blood pressure emerged as significant prognostic factors in ICH patients with CKD.
