  • Background The forehead, which occupies about one third of the face, is one of the major determinants of a feminine or masculine look. Various methods have been used for the augmentation of the forehead using autologous fat grafts or alloplastic materials. Methylmethacrylate (MMA) is the most appropriate material for augmentation of the forehead, and we have used an injection-molding technique with MMA to achieve satisfactory results. Methods Under local anesthesia with intravenous (IV) sedation, an incision was made on the scalp and a meticulous and delicate subperiosteal dissection was then performed. MMA monomers and polymers were mixed, the dough was injected into the space created, and manual molding was performed along with direct inspection. This surgery was indicated for patients who wanted to correct an unattractive appearance by forehead augmentation. Every patient in this study visited our clinics 3 months after surgery to evaluate the results. We judged the postoperative results in terms of re-operation rates caused by the dissatisfaction of the patients and complications. Results During a 13-year period, 516 patients underwent forehead augmentation with MMA. With the injection-molding technique, the inner surface of the MMA implant is positioned close to the underlying frontal bone, which minimizes the gap between the implant and bone. The borders of the implant should be tapered sufficiently until no longer palpable or visible. Only 28 patients (5.4%) underwent a re-operation due to an undesirable postoperative appearance. Conclusions The injection-molding technique using MMA is a simple, safe, and ideal method for the augmentation of the forehead.

  • Multiple osteochondromas (MO) is characterized by the formation of osteochondromas throughout the entire body. Although the evidence regarding its pathogenesis is well understood, no curative treatment for the disorder is available. Patients can be treated symptomatically by surgical removal of painful osteochondromas. Unfortunately, some patients still suffer from severe pain, even after surgery. We report on a case concerning a 48-year-old woman with a history of MO who presented with persistent pain after surgical removal of a symptomatic osteochondroma of the left scapula and multiple symptomatic osteochondromas of the left foot and trochanteric region. Several interventions to reduce the pain did not have any lasting effect. Subsequently, she was treated with autologous fat grafting (AFG). After each session she was pain-free for at least one year and reported only partial recurrence of the pain. This is the first case report describing AFG for the treatment of pain after both surgical removal of an osteochondroma and symptomatic osteochondromas in a patient suffering MO with promising results. The treatment is more effective and clearly continues to remain active longer than injection therapy or pain medication. Future studies are necessary to confirm our results.

  • Objectives: The rate of metabolic syndrome (MetS) in women diagnosed as they age is one of the main concerns of health cares. Recently new strategies used to prevent progressions of MetS toward the diagnosis of diabetes have focused on plant flavonoids. This study was aimed to investigate the beneficial effects of flavonoids fraction of Mespilus germanica leaves (MGL) on MetS in ovariectomized (OVX) rats. Methods: Twenty-four adult female Wistar rats, weighing 200 to 250 g, were divided into 3 groups: Sham surgery, OVX + Salin, or OVX + Flavonoid. Three weeks after ovariectomy, animals displayed MetS criteria received flavonoid injection (10 mg/kg, intraperitoneally) for 21 days. Then the body weight, body mass index, waist circumference, visceral fat, fasting blood glucose, serum insulin, lipid profiles and tumor necrosis $factor-{\alpha}$ ($TNF-{\alpha}$) were measured. Results: Treatment with flavonoids fraction of MGL significantly decreased serum level of insulin (P = 0.011), glucose (P = 0.024), $TNF-{\alpha}$ (P = 0.010), also MetS Z score (P = 0.020) and homeostasis model assessment of insulin resistance (P = 0.007). Lipid profiles and visceral fat showed insignificant reduction. Conclusions: Flavonoids of MGL attenuates some of the MetS components possibly via reduction in $TNF-{\alpha}$ inflammatory cytokine.

  • The goals of this study were, first, to evaluate the feasibility of inducing gastric perforation with 99% alcohol injection after electrocautery (EA-method), and, second, to observe "enhanced peritoneal stripe sign (EPSS)" and other lesions upon induction of gastric perforation. Six clinically normal beagle dogs were prepared for gastric perforation using endoscopy. After gastric perforation, EPSS and other lesions on ultrasonography were observed eventually (at 0 h, 3 h, day 1, day 2, day 3, day 4, day 5, and day 6). We graded the EPSS depending on its width and number. EPSS was observed until day 4 of the examination in all the 6 dogs. The grades of EPSS were the highest at 3 h and declined gradually. Peritoneal effusion was observed in all dogs at 3 h and on day 1. Regional bright mesenteric fat was confirmed in all dogs on days 3 and 4. In conclusion, gastric perforation can be induced by EA-method. EPSS and peritoneal effusion appear at a very early stage, and regional bright mesenteric fat was identified on days 3 and 4 in almost all dogs with gastric perforation.

  • Purpose: Adipose tissue injection as a free graft for the correction of soft - tissue deficiency or depression deformity is a widespread procedure in plastic surgery. This study is to analyze the changes and viability of cryopreserved adipose tissue and to find out efficient long - term storage period. Methods: After centrifugation of aspirated abdominal tissues, $10m{\ell}$ of packed Adipose tissue were freezed at $-20^{\circ}C$. For 2, 4, 6, 8 months, each frozen samples were taken and injected into scalp of SCID mice. After 15 weeks, injected Adipose tissue were sampled and analyzed at 2 months interval. We compared and analyzed each group about the weight of the injected fat, histologic impressions, activity of mitochondria, size of a fat cell and rate of survival. Results: Significant weight changes were observed in cryopreservation for 2 months(p<0.05). Histologic changes were observed, independent of the freezing period with H - E stain. Among cryopreservations for 2, 4, 6 months, no significant change were observed. The reduction of mitochondrial enzymatic activity was observed independent of time interval but activity of mitochondrial dehydrogenase was reduced less than 50% in MTT assay. Conclusion: Freezing in $-20^{\circ}C$ for 6 months has no adverse effect to Adipose tissue, but fragile adipocytes, damaged cell membrane during harvesting procedure, were disrupted within 1 - 2 month and the maximum volume reduction were followed less than 2 months. These results demonstrate that tissue preparation cells without membrane damage have the greatest viability level and cryopreservation less than 2 months has great volume effect and cryopreservation for 6 months has stable volume effect.

  • For studying the effect of different dietary fats on carcinogenesis, fatty acid composition of membrane and lipid peroxidation were measured. Male Sprague-Dawley rats were fed on diet containing 15%(w/w) beef tallow or soybean oil. A single dose of 50 mg 2-AAF/kg B.W. was injected i.p. in each diet group 10 times. Rats were sacrifled after 1, 5, 10, and 15 weeks from the first injection. By 2-AAF injection, !ipid peroxidation increased slightly compared to control group. The rats fed on different fats had similar MDA production and those fed on soybean oil had slightly higher free radical concentration measured by ESR. In young rats, iipid peroxidation level was high and hydroxy radical production was higher in soybean oil group than in beef tallow group. With age, the lipid peroxidation values were decreased initially then increased. The fatty acid composition in microsomal membrane was reflected by dietary fatty acid composition. In soybean oil group, monoenoic acid was lower and polyunsaturated fatty acid was higher than beef tallow group. Linoleic acid contents showed the most discrepancy among groups. By 2-AAF treatment, iinoleic acid content and unsaturation index increased in soybean oil group. But in beef tallow group, there was no difference in fatty acid contents.

  • To investigate the inhibitory effects of Citaowan (CTW) on the growth and angiogenesis of breast cancer in vivo. Orthotopic breast cancer model was established by injection of MDA-MB-231 cells into mammary fat pad of nude mice. Seven weeks after injection, CTW was orally administered at dose of 50, 100 mg/mouse every day for 40 days. Body weight, tumor volume, tumor apoptosis, microvessel density and tumor proliferation were evaluated, after the mice were sacrificed. The body weight and tumor volume were not significantly changed in CTW group compared with the control group. Tumor apoptosis, proliferation and microvessel density were significantly reduced in CTW group (100 mg/mouse) compared with the control group. These data indicate that CTW has anti-angiogenic and proapoptotic effects on breast cancer.

  • Azoxymethane (AOM) is a potent genotoxic carcinogen which specifically induces colon cancer. Hyperlipidemia and diabetes have several influences on colon cancer development, with genetic and environmental exposure aspects. Here, we investigated plasma lipid and glucose concentrations in Kunming mice randomized into four groups; control (no AOM or oil exposure), AOM control, AOM + pork oil, and AOM + canola oil. Aberrant crypt foci (ACF), plasma cholesterol, plasma triglyceride, plasma glucose and organ weight were examined 32 weeks after AOM injection. Results revealed that AOM exposure significantly increased ACF number, plasma triglyceride and glucose level. Further, male mice displayed a much higher plasma triglyceride level than female mice in the AOM control group. Dietary fat significantly inhibited AOM-induced hypertriglyceridemia, and canola oil had stronger inhibitory effect than pork oil. AOM-induced hyperglycemia had no sex-difference and was not significantly modified by dietary fat. However, AOM itself not change plasma cholesterol level. AOM significantly increased liver and spleen weight in male mice, but decreased kidney weight in female mice. On the other hand, mice testis weight decreased when fed canola oil. AOM could induce colorectal carcinogenesis, hypertriglyceridemia and hyperglycemia in Kunming mice at the same time, with subsequent studies required to investigate their genome association.
