Comparison of three different dosages of low-level laser therapy on expression of cell proliferation and inflammatory markers following ovariohysterectomy in rats.

The objective of the current study was to evaluate Low-level laser therapy (LLLT) on the healing of incisional wounds following ovariohysterectomy in rats, by means of subjective histopathological and immunohistochemical analysis. A total of 72 female Wistar rats were categorised into four treatment groups (Group I; sacrification 4 hours following only one LLLT application, Group II; sacrification 7 days following only one LLLT application, Group III; sacrification 4 hours after two LLLT applications, and Group IV; sacrification 7 days after two LLLT applications). Each group was further divided into four different doses subgroups (Group Control [C, off mode LLLT application], L [1 J/cm], L [3 J/cm], and L [6 J/cm]), with equal representation in each subgroup.

The effects of low-level laser therapy on polycystic ovarian syndrome in rats: three different dosages.

The main objective of this in vivo study was to investigate the effect of different low-level laser therapy (LLLT) doses on polycystic ovary syndrome (PCOS). In the present experimental study, a single dosage of estradiol valerate (EV) was administered to induce PCOS in female rats. After administration of the EV for induction of PCOS, rats were divided into 5 groups (n = 8/group): C group (animals that were not exposed to any form of procedure), PC group (no treatment following EV induction), L group (1 J/cm LLLT treatment following EV induction), L group (2 J/cm LLLT treatment following EV induction), L group (6 J/cm LLLT treatment following EV induction).

Association of luteal blood flow with follicular size, serum estrogen and progesterone concentrations, and the inducibility of luteolysis by PGF in dairy cows.

The aim of this study was to investigate the compatibility of the visual evaluation result of the blood flow characteristics and the blood flow measurements of the CL and the predictability of the responses given by corpora lutea with varying levels of blood flow to an induction of luteolysis by a PGF injection and to determine the possibility of increase in serum estrogen and progesterone concentrations in parallel with increased luteal blood flow (LBF). The cows, bearing a CL (n = 60; postpartum 35 days), were injected with PGF and were monitored for signs of estrous following the first injection. The cows, which did not show estrous signs, were examined for the presence of a CL on Day 14, whereas those that showed signs of estrous were examined on Day 10 following the onset of estrous.

Subclinical mastitis causes alterations in nitric oxide, total oxidant and antioxidant capacity in cow milk.

The aim of this study was to investigate total antioxidant (TAC), and oxidant capacity (TOC) and nitric oxide (NO) levels in milk of cows with subclinical mastitis. Brown Swiss and Holstein breed cows were screened with California Mastitis Test (CMT) to determine mammary glands with subclinical mastitis. Moreover, somatic cell counts (SCC) were determined electronically in all milk samples.
