AbstractIntroduction: The purpose of this study was to compare the effectiveness of four different suture techniques in the treatment of experimentally modelled tendon injuries with tissue loss with autograft and grafting applications in rabbits.Material and Methods: The study was performed on 30 male mature (2-year-old) New Zealand rabbits with mean body weight of 3.1 kg, divided into three equal groups. A graft measuring 1 cm in length was collected from the m. tibialis cranialis of each rabbit under general anaesthesia. The graft collected from the right tendon was transplanted into the left tendon, and the graft from the left tendon was transplanted into the right tendon. In all groups, a simple interrupted suture was placed on the left tendon as control, a Bunnell-Mayer suture was placed on the right tendon in group I, a Locking-Loop suture in group II, and a Horizontal U suture in group III. Both hindlimbs were bandaged for four weeks. The tendons were assessed biomechanically and histopathologically.Results: According to the results of the tensile testing, the maximum durability of the techniques ranked as follows: Bunnell-Mayer, Horizontal U, Locking-Loop, and control groups.Conclusion: The use of autografts was a good alternative for the treatment of tendon ruptures with tissue loss. Furthermore, even though there were no clinical or histopathological differences, the suture technique can be chosen based on the results of the tensile test.

And Control

The present study was conducted to investigate the efficacy of Ovsynch and Ovsynch plus protocol in postpartum (day 60) Sahiwal cows (n=18). Animals were randomly divided into three equal groups, viz., Ovsynch group Ovsynch plus group and Control group. Animals of group I (n = 6) were treated with traditional Ovsynch protocol. The animals (n = 6) of group II were treated with Ovsynch plus protocol which consisted of an initial intramuscular injection of eCG (Folligon) @ 250 IU on day 60 postpartum followed 3 days later by GPG (Ovsynch) protocol. In group-III Control, no treatment was given to animals (n = 6). Treated animals were inseminated at a fixed time between 14 and 20 hrs after second GnRH injection, irrespective of estrus detection. Blood samples were collected from each animal on days 50 and 60 postpartum to determine the status of cyclicity in animals based on serum concentrations of progesterone (P4). A third blood sample was collected on the day of prostaglandin treatment to determine the response of first GnRH injection. Four animals each were cyclic, and two were acyclic in both treatment groups. Four animals each responded to first GnRH treatment in both treatment groups. Similarly, two animals each got conceived giving conception rate of 50% (2/4) in each treatment. In the control group, one out of 6 animals got conceived yielding 16.66 % conception rate (1/6) during the study period. It may be thus concluded that Ovsynch and Ovsynch plus protocol may be used during the early postpartum period to improve the reproductive efficiency in postpartum Sahiwal cows.

The serum progesterone and estradiol profiles during synchronization of estrus by buck effect and PGF2α treatments were monitored in Surti does. Total eighteen non-pregnant does selected were evenly divided into 3 groups, 6 does in each group. The does of Group I were teased with a sexuallyactive- apronized buck; and those of Group II were treated with PGF2α, i.e., Inj. Lutalyse® @ 7.5 mg/doe IM twice 11 days apart, while the Group III served as untreated control. Blood samples were collected from all the animals on day 0 (before 1st PGF2α injection), 3rd day (during treatment), 11th day (before 2nd PGF2α injection), 14th day (after treatment) and 40th day (post-service) by jugular vein puncture. The serum separated was stored at -20°C till further analysis. In all the three groups, 83.33% does, conceived at first service in the sampling cycle. The overall mean serum progesterone concentration of Group I does (5.82±0.72 ng/ml) was significantly higher (p less than 0.01) as compared to Group II (2.93±0.38 ng/ml) and III (2.88±0.30 ng/ml). Similarly, the overall mean serum progesterone concentration of Surti does on day 0 (2.65±0.46 ng/ml), 3rd (2.56±0.80 ng/ml), 11th (4.45±0.84 ng/ml) and 14th (3.40±0.63 ng/ml) did not differ significantly, but the overall mean level at day 40 (6.31±0.45 ng/ml) was significantly (p less than 0.01) higher, because most of animals became pregnant at that time. The overall mean serum oestradiol-17β levels of Group I (24.40±2.98 pg/ ml) was significantly higher (p less than 0.01) than in Group II (15.77±1.77 pg/ml) and III (12.21±1.45 pg/ ml). On the other hand, the overall mean serum oestradiol-17β levels of Surti does on day 0 (12.89±1.21 pg/ml), 3rd (15.84±1.74 pg/ml), 11th (14.81±1.96 pg/ml), 14th (22.15±2.97 pg/ml) and 40th (21.64±5.16 pg/ml) did not differ significantly (p>0.05) and the slightly higher overall mean level found at 40th day might be the influence of the non-pregnant does at first service in the cumulative animals. The hormonal profile reflected the initiation of cyclicity and establishment of pregnancy in treated and control animals.

The action of electrically evoked activity in somatic afferent fibers on the sensitivity of the baroreceptor reflex was examined in decerebrate cats. The sensitivity of the reflex was expressed as the difference between the maximum prolongation of R-R interval in response to carotid sinus pressure elevation and the mean of 10 R-R intervals immediately before pressure elevation. The control value of R-R interval prolongation was 192 +/- 50 ms. Stimulation (10 Hz) of group I and II fibers of the right peroneal nerve (evoked volleys recorded from the sciatic nerve) had no effect on R-R interval prolongation (171 +/- 45 ms). Recruitment of group III fibers (10 Hz) conducting at 23.6 +/- 0.65 m/s reduced the prolongation of R-R interval to 52 +/- 14 ms. Recruitment of group IV fibers (10 Hz) conducting less than 2.5 m/s further reduced the prolongation of R-R interval to 1.0 +/- 8.0 ms. It is concluded that the inhibition of the cardiac vagal component of the baroreceptor reflex produced by electrical stimulation of the peroneal nerve is mediated by afferent fibers of groups III and IV.

Anaphylaxis is the most common allergic reaction triggered by allergens such as insect poisons, food, and drugs through skin contact, injection, or inhalation. In vitro previous research showed that strawberries fruit have activity as antioxidant, anticancer, anti-inflammation, and anti-allergic. The research aimed to determine the antianaphylaxis strawberry fruit extract in mice (Balb/C strain) with ovalbumin-induced.  Twenty-four Balb/C strain mice were divided into six groups (n=4). Group I and II as a normal and control group. Group III till VI as a treatment group was given cetirizine dose 0.042 mg/20 g BW and strawberry extract doses 0,68; 1,36; and 2,72 mg/20 g BW, respectively. This research showed that 70 % of ethanol extract of strawberries fruit have antiallergic activity in response to active cutaneous anaphylaxis. 70% ethanol extract of strawberries doses 2.72 mg/20 g BW had similar antiallergic activity compare with cetirizine. The conclusion of this study showed that strawberries fruit extract could be developed as an alternative medicine to anti-anaphylaxis or anti-allergic.

Intrinsic Cardiac Nerves

The intrinsic cardiac nerves (ICN) have been shown to develop supersensitivity to nicotine (NIC) following complete extrinsic cardiac denervation. The present experiments were performed to delineate the pattern of ICN distribution in the heart by examining the pattern of NIC supersensitivity after unilateral vagotomy (VGX). Thirty-eight dogs were placed on cardiopulmonary bypass and inotropy evaluated by means of isovolumic pressures from fluid-filled balloons placed in the atria and ventricles. The animals were divided into three groups: group I, sham-operated controls; group II, animals studied 1–2 wk after VGX; and group III, animals studied 8–12 wk after VGX. Chronotropic and inotropic responses were evaluated in terms of NIC and acetylcholine (ACh) dose-response curves as well as frequency-response curves to stimulation of the intact vagus nerve (0.5–30 Hz). No change in NIC sensitivity was observed in group II, and vagal frequency-response curves were identical to group I. In group III dogs, both the right atrium and right ventricle showed significant increases in NIC sensitivity after left vagotomy. All group III animals showed right-shifted frequency-response curves. We conclude that nicotinic supersensitivity of the ICN and inotropic unresponsiveness to vagal stimulation occur but are slow in developing (70–130 days); and preganglionic sprouting does not appear to play a functional role in the adjustment of cardiac control mechanisms to unilateral vagotomy.

The purpose of this study was to investigate the effectiveness of human bone morphogenetic protein-2 (BMP-2) expressing adenoviral vector in vivo. The day before vector injection, immunosuppressant FK506 was given subcutaneously to each rat at doses of 12 mg/kg (Group I), 6 mg/kg (Group II) and 3 mg/kg (Group III). FK506 was not administered to the six rats of the control group. Twenty-five liters of AXCAOBMP-2 (3.93 × 109pfu/ml) were injected into the right calf muscle of all rats. On day 21 after vector injection, all groups were investigated radiologically, histologically, and biochemically. Osteoinduction was seen in the AxCAOBMP-2-injected groups with immunosuppression. However, no bone formation was observed in the control group. These findings suggest that AxCAOBMP-2 has the potential of osteoinduction under transient immunosuppression. AxCAOBMP-2 may be useful for future clinical application in bone reconstruction, if host immunity response can be regulated.

Abstract The objective of the study was to determine how different birth weights of piglets influence some chemical and physical characteristics of pig meat. Piglets were grouped according to birth weight: ≤1.30 kg (group I), 1.31-1.70 kg (group II), ≥1.71 kg (group III). Animals were reared and fattened under standardized housing and feeding conditions. Tests were conducted with 60 samples of meat (20 per group) collected from the right side of the carcasses (M. longissimus lumborum) of threebreed crosses of (Polish Landrace × Polish Large White) × Duroc (barrows to gilts, 1:1), which were slaughtered at about 180 days of age. Determinations were made of basic chemical composition, colour of meat, drip loss, shear force value, and fatty acid profile. It was found that the birth weight of the piglets affects meat colour (redness), crude fat content and the proportion of some fatty acids (C16:1, C20:1 n-9, C20:2 n-6, C20:5 n-3).

This study compared the use of lyophilized glutaraldehyde-preserved bovine pericardium (LGPBP), polytetrafluoroethylene (PTFE), polyethylene terephthalate (PET), and Teflon felt (TF) as implants for vocal cords (VC) medialization and aimed to assess the endoscopic, macroscopic, and microscopic VC changes after medialization in a canine model. In 18 mongrel dogs, the right VC were medialized with LGPBP and the left were implanted as follows: Group I (n=6): LGPBP and PTFE; Group II (n=6): LGPBP and PET; Group III (n=6): LGPBP and TF. Surgical handling of the implants was compared. Three months after surgery, macroscopic and microscopic changes of VC and implants were evaluated. LGPBP offered the best surgical handling (p=0.005, Kruskal-Wallis). TF implants showed extrusion (p=0.005, Kruskal-Wallis) and severe inflammation. All VC formed fibrous capsules around the implants; the ones developed by LGPBP implants were thinner (p=0.001, ANOVA, Tukey). VC implanted with synthetic materials showed eosinophilic infiltration (p=0.01, Kruskal-Wallis). We concluded that the LGPBP could be used as an implant for VC medialization because it is biocompatible, easy to handle and remove during surgical procedures, and nonabsorbable or extrudable and produces an inflammatory reaction similar to PTFE and PET.
