  • Twelve docked and 12 intact Najdi lambs of equal numbers of males and females were slaughtered at 40 kg shorn shrunk body weight, Lipid in all empty body fat components; namely, subcutaneous, intermuscular, intramuscular, omental, mesenteric, channel, perirenal, pericardial, tail, viscera, bone and hide, were determined. Except for ram lambs, which had a lower percentage of lipid in intermuscular partition in loin cut, sex did not influence the relative proportion of subcutaneous or intermuscular fat in each wholesale cut. The data also showed that docking did not change the distribution of lipid in intermuscular and intramuscular fat partitions in each wholesale cut. Docked lambs tended to accumulate lower proportions of the lipid in subcutaneous fat component in the cuts located along the dorsal line than intact lambs. The total amount of lipid deposited in the empty body of ewe lamb was heavier in weight than that of ram lamb. Docking had no effect on the distribution of total lipid in the empty body, except for subcutaneous fat component, being greater in docked lambs than did intact ones. Generally, the highest proportion of fat was associated with subcutaneous depot followed, in order, by intermuscular, mesenteric, tail, intramuscular and omental fat partitions.

  • The influence of age on the relative growth patterns of subcutaneous, intermuscular, intramuscular, perirenal, channel and hump fat in relation to the total fat weight in carcass sides of 18 Najdi male camels averaging 8, 16 and 26 months of age has been investigated. The total fat weight in a carcass side increased (p<.01) from 17.3% to 27.1% as the camel age increased from 8 to 26 months. However, at all ages studied, intermuscular fat weight was the largest fat depot, followed, in order, by subcutaneous and intramuscular fat. The change in weight of the intramuscular, intermuscular and subcutaneous fat between 8 and 26 months of age was greater, reaching 6.7, 4.3 and 4 times respectively, than the hump, channel and perirenal fat weight which increased by 3.6, 2.5 and 2.3 times, respectively. The allometric growth coefficient (${\beta}$) for intramuscular fat in relation to the total carcass fat weight was the highest, followed, in order, by intermuscular, subcutaneous, hump, channel and perirenal fat.

  • The experiment was conducted to study the effects of water soluble vitamins and retinoic acid on the differentiation of preadipocyte from omental, subcutaneous, intermuscular and intramuscular adipose tissue of Hanwoo. Differentiation was assessed by the change in enzyme activity, glycerol-3 phosphate dehydrogenase in serum free cell culture system. Preadipocytes treated with biotin ($10{\mu}M$) and pantothenic acid ($100{\mu}M$) were significantly (p<0.05) less differentiated than those from the control in all adipose tissue depots except intramuscular tissue. Although there was no significance, vitamin C was shown to stimulate the adipocyte conversion in omental and subcutaneous, but not in intermuscular and intramuscular adipose tissues. Lower values of GPDH activity in intermuscular preadipocyte were interpreted to be caused by relatively higher amounts of protein. In this experiment vitamin C did not stimulate fat deposition in intramuscular adipose tissue but further experiments are needed on the role of vitamin C in preadipocyte differentiation. When treated with different levels of retinoic acids, differentiation of preadipocytes was significantly (p<0.05) reduced from the level of $0.5{\mu}g/ml$ in omental and intermuscular, from $50{\mu}g/ml$ in subcutaneous, and in intramuscular at $500{\mu}g/ml$, thus showing that intramuscular preadipocytes were least responsive to retinoic acid in differentiation. All-trans retinoic acid appeared to inhibit the differentiation in a dose dependent manner, regardless of adipose tissues type.

  • Schwannomas are mostly solid tumors, some of which may contain cystic degenerations or hemorrhages. However, a schwannoma seen as a purely hemorrhagic cystic tumor is very rare. A 63-year-old woman was referred to the hospital due to a slow-growing mass (present for about 5 years) on her right thigh. She complained about vague pain but without neurologic symptoms such as numbness or tingling sensations. MR images showed an oval lesion with defined margins surrounded by the rectus femoris, vastus lateral, and the vastus intermedius. It was characterized as a multilocular cystic lesion composed of hemorrhagic fluid. In addition, the benign hemorrhagic cystic lesion was differentially diagnosed by radiological techniques as a hemorrhagic ganglion cyst. The lesion was surgically excised and, based on pathological features, was diagnosed as being a schwannoma. We report a purely hemorrhagic cystic schwannoma located in an intermuscular plane.

  • Live animal selection programs that favor animals with a minimum amount of carcass fat are used for improving breeding flocks of sheep. To predict carcass characteristics of live sheep using body measurements in breeding flocks, 200 male and female lambs of two fat-tailed Iranian sheep breeds (Moghani and Makui) were used. Depth of soft tissue over the 12th rib of the live animals was measured with ultrasound (ULGR) and with hypodermic needle (NGR). The height at withers (HW), body length (BL), circumference of heart girth (CH) and width of hooks (WH), were measured. All animals were slaughtered; carcasses were cut into joints and dissected. Breed had a significant effect on all of the live easurements. The Moghani breed showed a higher value for HW, CH, ULGR and NGR, compared to that of Makui. Except for soft tissue depths; ULGR, NGR and GR, the male lambs showed higher values in live and carcass measurements than females. Percentages of carcass, total fat and intermuscular fat in females were higher than that of male lambs. In spite of the higher amount of subcutaneous and intermuscular fat in female (which is usually used for their physiological need, such as pregnancy and lactation), the male lambs had a heavier fat-tail than females. There was a wide range of variation of percentage of total carcass fat and total chemical fat content of carcass in the two breeds. Eventually this wide variation could be use by animal breeders for selection of animals with a lesser amount of carcass fat. Live weight of lambs showed a relatively low correlation with percentage of carcass lean, total fat and subcutaneous and intermuscular fat. Total lean meat was predicted with relatively high coefficients of determination in the two breeds ($R^2$=0.61 and 0.89, respectively). Live weight and carcass traits were predicted using simple measurements, but with $R^2$ ranging from 0.53 to 0.93.

  • This study was designed to determine the effects of the insulin-like growth factor (IGF-1) and estradiol $17-{\beta}$ on the in vitro proliferation of stromal vascular cell from Hanwoo omental, subcutaneous, intermuscular and intramuscular adipose tissues. Cells were cultured in M199+20% newborn calf serum and the proliferation of cells was measured by direct microscopic cell counting and change of genomic DNA amount. Cell numbers increased slightly over the first 72 hour of culture and then increased greatly, regardless of adipose tissue depots. In IGF-1 treatment, the number of omental preadipocytes maintained highest level from the beginning to the 20th day of culture. However, in estradiol-$17{\beta}$ treatment, those tended to be lower than the control from the beginning of culture and significantly lower at the 24th day. When IGF-1 was added to subcutaneous preadipocytes, the numbers of cells were higher from 11th day than those from other treatments, although there was no statistical significance. For intermuscular preadipocytes treated with IGF-1, its numbers were significantly (p<0.05) higher at 11th day, and in the other days it showed a similar tendency to those of the subcutaneous tissue. In this experiment, preadipocytes were taken from 24 month old fully matured steers and the highest proliferation rate was shown in intramuscular tissue followed by those of subcutaneous preadipocytes. Addition of $5{\mu}M$ estradiol-$17{\beta}$ to the growth medium failed to promote the replication of Hanwoo preadipocytes, as indicated by direct cell counts and total genomic DNA content. As the culture period proceeded, the amounts of DNA were increased, but the patterns of increment were not consistent with the results of cell numbers.

  • Lipomas make up $4{\sim}5%$ of all benign tumors in the body and are most often located on shoulders and backs. Neck lipomas are often developed in the subcutaneous tissues of the posterior neck, Most lipomas have slow growth rate and the recurrence is very rare after surgical excision because of well-defined border. But lipoma originated from muscles(intramuscular and intermuscular lipoma), so called infiltrating lipoma, has ill-defined border and little or no evidence of encapsulation. Histologically the feature of infiltrating lipoma is distinctive. There is a consistent infiltration with dissociation of the surrounding muscle fibers. The overall recurrence rate is less than 5%, but rises to 62.5% when deep infiltrating lipomas are considered separately. Thus infiltrating lipoma is best excised with a margin of normal muscle to avoid recurrence. Its location in the head and neck is uncommon. 18 cases of infiltrating lipoma in the head and neck has been reported to date. Here we report a case of infiltrating lipoma that arises in the head and neck muscle with a review of the literature on the subject.

  • The present studies were designed to provide new information on fatty acid profiles of various muscles and adipose tissues of fattening horses in comparison with beef cattle and pigs. In the first study, the lipids were extracted respectively from subcutaneous, intermuscular adipose tissues, longissimus dorsi and biceps femoris muscles of fattening Breton horses (n = 8) with an average body weight of 1,124 kg. In the second study, the lipids were extracted from subcutaneous, intermuscular adipose tissues and longissimus dorsi muscle of fattening horses (n = 13), Japanese Black beef cattle (n = 5), Holstein steers (n = 5) and fattening pigs (n = 5). The fatty acids in the lipid samples were determined by gas chromatography after methylation by a combined base/acid methylation method. It was found that the lipids from horse subcutaneous and intermuscular adipose tissues contained more (p<0.05) polyunsaturated fatty acids (PUFA) which were mainly composed of linoleic acid (C18:2) and linolenic acid (C18:3) than those in the muscles. The weight percent of conjugated linoleic acids (CLA cis 9, trans 11) in lipids from biceps femoris muscle was 0.22%, which was higher (p<0.05) than that from the other depots. The horse lipids were higher (p<0.05) in PUFA but lower (p<0.05) in SFA and MUFA in comparison with those of the cattle and pigs. The percentage of C18:2 or C18:3 fatty acid in the horse lipids were respectively 2-8 fold or 5-18 fold higher (p<0.05) than those of the cattle and pigs. The percentages of CLA (cis 9, trans 11) in the horse lipids (0.14-0.16%) were very close to those of the pigs (0.18-0.19%) but much lower (p<0.05) than those of the Japanese Black beef cattle (0.55-0.94%) and Holstein steers (0.46-0.71%). The results indicated that the fatty acid profiles of lipids from different muscle and adipose tissues of fattening horses differed significantly. In comparison with that of the beef cattle and pigs, the horse lipids contained more C18:2 and C18:3 but less CLA.

  • The present study was conducted to investigate the supplementation effects of $C_{18:2}$ rich-soybean oil or $C_{18:3}$ rich-perilla oil (7% of total diet, DM basis) for 12 weeks on plasma metabolites, fatty acid profile, in vitro lipogenesis, and activities of LPL and FAS in adipose tissue of sheep. The treatments were basal diet (Control), $C_{18:2}$ rich-soybean oil supplemented diet (SO-D) and $C_{18:3}$ rich-perilla oil supplemented diet (PO-D). All the sheep were fed the diets consisting of roughage to concentrate in the ratio of 40:60 (DM basis). Oil supplemented diets (SO-D and PO-D) slightly increased contents of triglyceride (TG) and total cholesterol (TC), proportions of both cis-9 trans-11 and trans-10 cis-12 CLA and TVA, but lowered (p<0.01) those of $C_{18:0}$ compared to the control diet. No differences were observed in the contents of TG and TC and proportions of fatty acids in plasma between supplemented oils. Oil supplemented diets slightly increased the proportions of cis-9 trans-11 and trans-10 cis-12 types of CLA in subcutaneous adipose tissue of sheep compared to the control diet. The rate of lipogenesis with acetate was higher (p<0.01) for intermuscular- and subcutaneous adipose tissues than that for intramuscular adipose tissue, while that with glucose did not differ among fat locations in sheep fed SO-D. No differences were observed in the rate of lipogenesis between substrates in all fat locations. The rates of lipogenesis with glucose increased only in the intermuscular- (p<0.01) and subcutaneous adipose tissue (p<0.005) compared to those with acetate. The rates of lipogenesis with acetate were the highest in the intermuscular and intramuscular adipose tissue of the sheep fed PO-D. Oil supplemented diets slightly increased the rate of lipogenesis with glucose for all fat locations. Supplementation of oils to the diet numerically increased the fatty acid synthase activity but did not affect the lipoprotein lipase activity in subcutaneous adipose tissue.
