Ionic Strength Effects on Heat-induced Gelation of Myofibrils and Myosin from Fast- and Slow-twitch Rabbit Muscles

The effects of ionic strength on myofibrils and myosin from rabbit fast-twitch Psoas major (PM) and slow-twitch Semimembranosus proprius (SMp) muscles before and after heating were studied by electron microscopy and thermal scanning rheometry. The direct suspension of proteins in low ionic strength (0.2M KCl; pH 6.0) led to very weak gels, whereas a gradual lowering of the ionic strength (by dialysis against 0.2M KCl; pH 6.0) of 0.6M KCl protein solutions induced strand-type networks at low temperature and strong heat-induced gels. As shown by transmission and scanning electron micrographs, in low ionic strength, SMp myosins formed shorter filaments before heating and thinner and shorter structures in heat-induced gels, as well as a lower gel porosity than PM myosins.     

Misidentification by wild rabbits,Oryctolagus cuniculus,of group members carrying the odor of foreign inguinal gland secretion

To demonstrate that the inguinal gland odor conveys information on the identity of individuals, 60 male, wild-type rabbits,Oryctolagus cuniculus, living in groups of three in outdoor pens, were used in 120 tests. Members of the groups smeared with the inguinal gland secretion from unfamiliar rabbits were attacked by their penmates. In contrast the odors of chin gland secretions and urine of strange rabbits and of a commercial perfume did not cause serious disruption to the social relationships within the groups.     

兔肉香肠中乳酸菌分离与发酵特性的研究

从传统自然发酵兔肉香肠中分离得到3株乳酸菌L26、L34和L106经鉴定分别为植物乳杆菌（Lactoba—cillus．plantarum）、清酒乳杆菌（L．sake）和果糖乳杆菌（L加”蜘淞）。对其发酵特性的研究表明：3株茵均有良好的产酸能力、耐盐能力、耐亚硝酸盐能力和抑菌性能,相互之间无拮抗作用,可作为发酵兔肉用混合发酵剂。     

高强度聚焦超声损伤兔肌肉组织的超声影像学变化的初步研究

探讨高强度聚焦超声损伤兔肌肉组织的超声图像变化。采用高强度聚焦超声经皮照射20只新西兰大白兔双侧后肢肌肉,其中18只于照射前1d、照射后10min、照射后1d,3d,7d,14d,21d,28d进行二维超声、彩色多普勒和能量多普勒超声检查,并于照射后28天处死后测量凝固灶大小。另2只分别于照射后1d及照射后50d解剖,行病理学检查。(1)HIFU照射后凝固灶外周可见强回声带至低回声带的演变过程。(2)HIFU照射后第1d,测量的凝固灶体积最大(1476.59±308.64mm3),第3d～第21d,凝固灶体积逐渐缩小(612.47±127.98mm3)。第28d凝固灶体积最小(343.29±54.79mm3)。超声检查在兔肌肉组织HIFU照射后的随访中发挥了重要的作用,为监测HIFU治疗人体软组织肿瘤超声图像的变化提供了实验依据。     

Partial replacement of sodium chloride with potassium chloride in marinated rabbit meat

This study was aimed at evaluating the consequences of sodium chloride reduction by potassium chloride up to 50% on technological, sensorial and microbiological traits of marinated rabbit meat. In total, 226 rabbit loin meat samples were obtained and subjected to vacuum tumbling using solutions with different NaCl/KCl ratios. Replacing of sodium chloride up to 30% by potassium chloride did not change microbiological traits (total aerobic mesophilic and lactic acid bacteria maximum cell loads), sensorial acceptability (perceived saltiness and overall liking) and technological traits (pH, colour, texture, cooking loss and yield). Otherwise, reduction in sodium chloride to 50% significantly decreased perceived saltiness (4.15 vs. 4.73; P < 0.05) and reduced microbial shelf life by 1 day when compared to control, even if there was still no effect on technological traits. In conclusion, it is feasible imparting an added value for processed rabbit meat products by reduction in sodium content that could increase market interest.     

Preparation,characterisation and structure of rabbit (Hyla rabbit) skin gelatine

Rabbit skin was used as a raw material to prepare gelatine. The yield of extracted rabbit skin gelatine was 8.49 ± 0.91% based on a wet weight basis. The bloom strength of 6.67% rabbit gelatine was 457.57 ± 3.302 g, and its gelling and melting temperatures were 27.8 and 34.4 °C, respectively. Sodium dodecyl sulphate‐polyacrylamide gel electrophoresis analysis demonstrated that the content of the subunit components (α chain, β and γ components) of the rabbit skin gelatine achieved 97.915%. Amino acid composition analysis indicated that the total amino acid contents (proline plus hydroxyproline) in the rabbit gelatine were 222 residues per 1000 residues. The high content of the subunit components and amino acids could contribute to the gelatine's suitable gel properties. Rabbit gelatine had nearly all of the characteristic absorption peaks of collagen from rabbit skin, and the loss of the triple helical structure and damage to part of the hydrogen bonds occurred during the conversion of collagen to gelatine.     

Hippocampal theta-band activity and trace eyeblink conditioning in rabbits.

The authors examined the relationship between hippocampal theta activity and trace eyeblink conditioning. Hippocampal electrophysiological local field potentials were recorded before, during, and after conditioning or explicitly unpaired training sessions in adult male New Zealand White rabbits. As expected, a high relative power of theta activity (theta ratio) in the hippocampus predicted faster acquisition of the conditioned response during trace conditioning but, contrary to previous results obtained using the delay paradigm, only in the initial stage of learning. The presentation of the conditioned stimulus overall elicited an increase in the hippocampal theta ratio. The theta ratio decreased in the unpaired group as a function of training, remained high throughout conditioning in the fast learners, and rapidly increased in the slow learners initially showing a low theta ratio. Our results indicate a reciprocal connection between the hippocampal oscillatory activity and associative learning. The hippocampal theta ratio seems to reflect changes and differences in the subjects’ alertness and responsiveness to external stimuli, which affect the rate of learning and are, in turn, affected by both conditioning and unpaired training.
