Background Most women consider an oval-shaped face to be youthful and beautiful. In recent years, demand has grown for surgical procedures with a shorter downtime and fewer complications. These minimally invasive procedures include botulinum toxin type A (BoNTA) injection, filler injection, suction-assisted liposuction (SAL), laser-assisted lipolysis (LAL), thread lifting, and fat grafting. This study aims to introduce an effective method for creating an aesthetically pleasing lower face using a combination of minimally invasive procedures. Methods From March 2017 to March 2019, 94 patients simultaneously underwent LAL, SAL, and thread lifting. Ancillary procedures such as BoNTA injections, hyaluronic acid filler injections, and removal of the buccal fat pad (BFP) were selectively performed according to the patient's condition. Results Patients rated their postoperative satisfaction as very satisfied, satisfied, dissatisfied, or very dissatisfied. Approximately 83% of all respondents were satisfied with the results, whereas the remaining respondents had complaints regarding the outcomes. The most common reasons for dissatisfaction were a longer-than-expected recovery time and undercorrection, and the most severe complaint was skin depression as a result of overcorrection. Conclusions Our method of simultaneously performing LAL, SAL, and thread lifting, while adding BoNTA, filler injections, and BFP removal as needed, was capable of producing consistent and reliable aesthetic outcomes for the lower face.

The purpose of this study was to observe the microscopic change of salivary gland tissues, which is the cause of xerostomia in diabetic condition: for this target the author injected STZ 0.1ml/100gm b.w. on rat to produce diabetes, and than observed microscopic change in submandibular gland through the histopathologic method, obtaining as follows : 1. All of the experimental specimens suffered diabetes after injection of STZ, but the blood glucose level was irregular. 2. There were not interrelationship between the blood glucose level and microscopic change on salivary gland tissues. 3. The salivary gland changed after diabetes initiation in lapse of times; after 14 days,suffered severe destruction, however after 17 days, it was regenerated. 4. Salivary glands showed congested, destructive acini cells, and hyperplastic ductal cells as well as salivary gland duct-like structures. 5. Then were accumulation of fat granules within the cytoplasm of the acini cells on mucous gland in diabetic condition. 6. According to insulin injection, there were no more changes on salivary gland tissues, even in the accumulation of fat granules. 7. Histological changes of the serous gland were obvious more than the mucous gland in this experimental condition.

Background: Various substances are currently being used for cosmetic or postsurgical reconstruction reasons. Injecting of various materials into the face may provoke inflammatory or granulomatous reactions, infection and tissue necrosis. Among these reactions are foreign body granulomas. This study aims to describe the clinical characteristics of and therapeutic approaches used in patients with facial foreign body granulomas caused by the injection of various substances. Methods: From 2007 to 2020, a total of 64 patients visited our hospital due to inflammatory signs, palpable masses or surface irregularities. We reviewed patient characteristics, type of injected material, medical history and treatment outcomes. The treatment results were scored with patient satisfaction and statistical analysis of the treatment period was performed. Results: Most patients underwent conservative treatment followed by surgical treatment because of persistent symptoms; one patient did not require surgery. All patients reported good treatment results and satisfaction. The earlier the surgical treatment was performed, the shorter the treatment period and the higher patient satisfaction scoring. Conclusion: Granulomatous changes to the face are an emerging concern in various cosmetic procedures and surgeries, including fillers, silicone implants and autologous fat injections. Our findings strongly suggest that patient symptoms require accurate diagnosis and surgical treatment.

본 연구는 LUT이 고지방식이로 비만이 유도된 C57BL/6 마우스의 대장암 발생에 미치는 영향을 분석하기 위해 실험동물을 각 10마리씩 정상식이 (ND)군, 고지방식이 (HFD)군, HFD + 0.0025% LUT 보충 (HFD LL)군, 그리고 HFD + 0.005% LUT 보충 (HFD HL)군의 4군으로 분류하였다. 각 실험군은 AOM을 1회 복강 주사하고 AOM 투여 1주일 후 총 3 cycle의 1 ~ 2% 농도의 DSS를 음용수로 공급하여 대장암을 유발하였다. 실험식이는 AOM 발암시점부터 총 11주간 급여하였다. 연구결과, 군간 식이섭취량의 차이는 없었으나 HFD 급여군에서 체중과 식이효율의 유의적인 증가가 나타났으며 HFD군과 비교했을 때 LUT 보충에 따른 체중의 변화는 없었다. 그러나 LUT 보충은 ND군에 비해 HFD군에서 나타난 대장 무게/길이 비, 대장종양 수, 혈장 $TNF-{\alpha}$ 농도, 대장 iNOS와 COX-2 발현을 유의적으로 감소시켰으며 그 효과는 HFD HL군이 HFD LL군보다 높았다. 이러한 결과는 체중조절과는 별개로 LUT이 고지방식이에 의한 대장의 염증반응 억제를 통하여 비만과 연관된 대장암 발생을 억제할 수 있음을 제시하며 향후 비만에 의한 인슐린 저항성 및 adipokine 분비, 그리고 장내 균총 변화에 따른 대장 점막세포 증식과 대장암 발생에 LUT이 어떤 영향을 미치는지에 대한 연구를 더 깊이 있게 수행한다면 비만으로 인한 대장암 발생에 LUT이 효과적인 화학적 예방 (chemoprevention)제로 활용될 수 있을 것으로 기대한다.

Temporal hollowing is a common complication that occurs after coronal approach surgeries. However, temporal hollowing without previous nerve damage or trauma history is rare. Herein, we present a patient with cryptogenic temporal hollowing. A 22-year-old man without any history of craniofacial interventions or trauma presented with temporal hallowing. Magnetic resonance imaging revealed fatty degeneration of the left temporalis muscle. Electromyography and nerve conduction study showed no signs of neurologic abnormalities. The patient received autologous fat injection of 30 mL harvested from the left thigh using the modified Coleman technique. Temporal hollowing is commonly caused by atrophy of the superficial temporal fat pad. Its incidence is reported to be as high as 6% after coronal approach operation. Augmentation using porous hydroxyapatite or titanium mesh is a treatment option. Autologous fat graft can also be an option for mild to moderate temporal hollowing. In this case, a patient with no history of trauma, surgery, or myogenic disease developed temporal hollowing. Further study of the little-known cryptogenic form of temporal hollowing is warranted.

Objectives: The purpose of this study was to determine whether gocho (苦椒) extract mesotherapy can effectively reduce weight and abdominal fat in obese patients. Methods: Forty obese participants were recruited and randomly assigned to two groups. Five participants dropped out voluntarily during the course of the study and four men were excluded from the analysis to avoid gender bias. Results are presented on a total of thirty-one women. Over an eight-week period, the treatment group (n=13) received gocho (苦椒) extract injections (100mcg/3cc) in the abdominal skin, twice per week; the control group (n=18) received normal saline injections (3cc). A mixed lidocaine and prilocaine cream (2.5%/2.5% EMLA cream) was applied before the injection. At baseline and 8 weeks, body weight, body-mass index (BMI), waist circumference (WC), waist-hip ratio (WHR), abdominal fat, energy expenditure, and questionnaires (eating attitudes and physical activity) were evaluated in both groups. Results: Reductions in body weight (p<0.005), BMI, and WC (p<0.05) were greater in the treatment group. WHR, total fat area, and visceral fat area decreased only in the treatment group (p<0.05). Resting metabolic rate (RMR) change was correlated with weight loss only in the control group (r=-0.498, p<0.05). Before and after the treatment, there were no significant differences between the two groups in questionnaire variables (p>0.05). Conclusion: his study suggests that abdominal gocho (苦椒) extract mesotherapy might be an effective way to promote weight and abdominal fat loss in obese Korean women.

As the popularity of fat grafting research increases, animal models are being used as the source of pre-clinical experimental information for discovery and to enhance techniques. To date, animal models used in this research have not been compared to provide a standardized model. We analyzed publications from 1968-2015 to compare published accounts of animal models in fat grafting research. Data collected included: species used, graft characteristics (donor tissue, recipient area, amount injected, injection technique), time of sacrifice and quantification methods. Mice were most commonly used (56% of studies), with the "athymic nude" strain utilized most frequently (44%). Autologous fat was the most common source of grafted tissue (52%). Subcutaneous dorsum was the most common recipient site (51%). On average, $0.80{\pm}0.60mL$ of fat was grafted. A single bolus technique was used in 57% of studies. Fat volume assessment was typically completed at the end of the study, occurring at less than 1 week to one year. Graft volume was quantified by weight (63%), usually in conjunction with another analysis. The results demonstrate the current heterogeneity of animal models in this research. We propose that the research community reach a consensus to allow better comparison of techniques and results. One example is the model used in our laboratory and others; this model is described in detail. Eventually, larger animal models may better translate to the human condition but, given increased financial costs and animal facility capability, should be explored when data obtained from small animal studies is exhausted or inconclusive.

Cattle in Alaska seemed to be tolerant to low blood selenium (Se) although arctic winter energy demands might exacerbate oxidative damage to tissues lacking protection by Se. The thermogenic properities of brown adipose tissue (BAT) and the long cold adaptation period for Alaskan cattle indicates that they might develop BAT. Eighteen mature beef cows with whole blood Se of< 19 ppb were used to examine possible relation-ships among Se deficiency, tissue lesions, and observable BAT. All cows were wintered on a diet low in Se and nine cows were given supplemental Se provided by intraruminal bolus. Blood Se was elevated (p < .05) from November through February by supplemental Se, but body weight and back fat thickness were unaffected (p < .10). Tissues were taken from two Se deficient cows, two cows supplemented with Se, and two cows given large doses of Se (300 mg by injection) four weeks before slaughter. Histopathological examination of 187 samples of fat (7 to 55 from each cow) showed no observable amount of BAT. Examination of other tissues showed no lesions attributable to Se deficiency.

Saponin, essential oil and fat oil fractions were fractionated from Panax Ginseng and their potentiating or inhibiting actions during the combined use of several central nervous system stimulants or depressants were observed to elucidate the possible role of Ginseng fractions on the central nervous system. Saponin, essential oil and fat oil fractions shortened nembutal sleeping time at low dosage (10 mg/kg) but contrarily they produced potentiation of nembutal hypnosis at high dosage (50mg/kg). In the toxicity study of amphetamine, saponin and essential oil fractions reduced the toxicity in aggregated mice at high dosage (100 mg/kg) but such decreased lethality was not observed in isolated mice. Ginseng fractions, especially high dose of saponin fraction (100mg/kg) prolonged the survival time after injection of convulsive dose of metrazol or cocaine and saponin fraction also prolonged the onset of cocaine convulsion at high dosage (100 mg/kg).
