This study was performed to investigate the body image perception by BMI and the dietary behaviors in 803 college students (408 males and 395 females). The degree of obesity was divided into an underweight group with BMI less than 18.5 kg/m(2), a normal group with BMI of 18.5~22.9 kg/m(2), an overweight group with BMI of 23~24.9 kg/m(2) and an obese group with BMI over 25.0 kg/m(2). The average ages of subjects were 22.9 years in males and 20.2 years in females. The average weight and height of male subjects were 175.3 cm and 69.6 kg, respectively and those of female subjects were 162.5 cm and 52.0 kg, respectively. The average BMIs of male and female subjects were 22.6 kg/m(2) and 19.7 kg/m(2), respectively. The distribution of subjects who perceived their current body image as ideal body image was 25.7% in males and 10.9% in females, showing that the body image satisfaction of male subjects was 1.5 times higher than that of female subjects. Body image perception for their own bodies was mostly shown as the average or standard shape both in males and females with 64.2% and 54.2%, respectively, but males showed a higher perception rate than females and 31.1% of females and 19.5% of males perceived their bodies as lean shape (p < 0.01). The body image satisfaction was 4.20 in males and 3.70 in females, showing more satisfaction in the male subjects (p < 0.001). The correlation between body image and physical variables in male subjects indicated that CBI and IBI showed statistically significant correlation and also BMI showed statistically significant correlation with IBI (p < 0.001) and CBI (p < 0.001). The frequency of eating out increased as the frequency of skipping meals increased (p<0.001) and the frequency of having snacks increased as the frequency of eating out increased (p < 0.01). The correlation between body image and physical variables in female subjects showed that CBI and IBI (p < 0.001) had statistically significant correlation. Body weight showed statistically significant correlation with CBI (p < 0.001), BMI (p < 0.001) and height (p < 0.001). The frequency of eating out increased as height (p < 0.01) and the frequency of skipping meals (p < 0.001) increased. When both male and female subjects wanted leaner body shapes, they preferred much leaner shapes despite their current body images belonging in the normal range. Additionally subjects preferred the body image in the normal range in cases when their current body images were lean. In particular, more female subjects had strong desires to become leaner in their body images than male subjects, which could be analyzed as a risk factor for physical harm. From the above results, it is considered that both male and female subjects need to establish proper recognition and dietary behaviors for their body images and also need nutritional education and counseling for desirable weight control methods.

2.Anticancer effect of metformin alone and in combination with 2-deoxy-D-glucose on mouse T cell lymphoma EL4 cells
Korean Journal of Veterinary Research 2023;63(3):e30-
Metformin is a treatment used widely for non-insulin-dependent diabetes mellitus with few side effects and acts by inhibiting hepatic gluconeogenesis and glucose absorption from the gastrointestinal tract. Lymphoma is one of the most common hematological malignancies in dogs. Chemotherapy is used mainly on lymphoma, but further research on developing anticancer drugs for lymphoma is needed because of its severe side effects. This study examined the anticancer effects of metformin alone and in combination with 2-deoxy-D-glucose (2-DG), a glucose analog, on EL4 cells (mouse T-cell lymphoma). Metformin reduced the metabolic activity of EL4 cells and showed an additive effect when combined with 2-DG. In addition, cell death was confirmed using a trypan blue exclusion test, Hochest 33342/propidium iodide (PI) staining, and Annexin V/PI staining. An analysis of the cell cycle and mitochondria membrane potential (MMP) to investigate the mechanism of action showed that metformin stopped the G2/M phase of EL4 cells, and metformin + 2-DG decreased MMP. Metformin exhibited anticancer effects as a G2/M phase arrest mechanism in EL4 cells and showed additive effects when combined with 2-DG via MMP reduction. Unlike cytotoxic chemotherapeutic anticancer drugs, metformin and 2-DG are related to cellular glucose metabolism and have little toxicity. Therefore, metformin and 2-DG can be an alternative to reduce the toxicity caused by chemotherapeutic anticancer drugs. Nevertheless, research is needed to verify the in vivo efficacy of metformin and 2-DG before they can be used in lymphoma treatments.
4.Lactobacillus johnsonii JERA01 upregulates the production of Th1 cytokines and modulates dendritic cells-mediated immune response
The Korean Journal of Physiology and Pharmacology 2025;29(3):271-281
Lactic acid bacteria are known to have various effects on the immune system. The type and extent of the effect differ, depending on the type of lactic acid bacteria. This study aimed to investigate the effects of Lactobacillus johnsonii bacterin on mouse-derived immune cells. Treating splenocytes with L. johnsonii bacterin slightly increased the metabolic activity. Additionally, the expression of the activation marker CD25 and production of the Th1-type inflammatory cytokine interferon (IFN)-gamma increased. We confirmed that the increase in IFN-gamma production due to L. johnsonii stimulation was mainly due to T and B cells among splenocytes. Treating dendritic cells (DCs) with L. johnsonii bacterin at concentrations of 10 6 and 10 7 cfu/ ml significantly increased tumor necrosis factor-alpha, a pro-inflammatory cytokine, and interleukin-12, a cell-mediated immunity cytokine. Additionally, the expression of surface markers increased. Allogeneic mixed lymphocyte reactions showed that L. johnsonii reduced the antigen-presenting ability of DCs. In cocultures of DCs and splenocytes, L. johnsonii decreased cellular metabolic activity and increased cell death. L. johnsonii upregulated the expression of programmed death ligand 1 on DCs. The findings of this study indicate that L. johnsonii bacterin has immunomodulatory and immunostimulatory effects. While L. johnsonii increased the expression of cytokines and surface markers of immune cells, it modulated DC-mediated immune response. Further studies are needed to determine the effects of L. johnsonii bacterin on DCs and related immune cells.

Wells' syndrome was first described by Wells in 1971 as a recurrent granulomatous dermatitis with eosinophilia and was later named eosinophilic cellulitis. It is defined by the following criteria: sudden onset of annular or circinate erythematous-edematous patches that rapidly evolve to morphea-like blue-slate-colored plaques; a histological feature characterized usually by the presence of 'flame figures'; non-constant blood hypereosinophilia. We present clinical and histopathologic features of three cases of eosinophilic cellulitis.

Tumor necrosis factor (TNF)-alpha is suggested to play a major role in the pathophysiology of psoriasis. Excellent clinical responses of psoriasis to anti-TNF-alpha-based therapies have recently been demonstrated. We studied the effect of combination therapy of infliximab, methotrexate, and retinoid in recalcitrant pustular psoriasis. A 34-year-old woman with a 1-year history of severe pustular psoriasis, who had not responded to conventional therapies, responded rapidly to combination treatment with infliximab, methotrexate, and retinoid. The clinical response was ascertained by the PASI gap (Psoriasis area and severity index) and the VAS gap (Visual affected sign). The findings showed that all the pustular lesions faded away after a single combination therapy treatment, and there has been no recurrence of pustular psoriasis for 8 months since initial injection. Thus, we conclude that the combination therapy of infliximab, methotrexate, and retinoid is an effective therapy for severe recalcitrant pustular psoriasis which does not respond to conventional therapies.
