Abstract
We describe a probable recessive X-linked myopathy characterized by the presence of vacuolated muscle fibers. Four males and their shared maternal grandfather were affected. Clinical characteristics include juvenile onset, very slow progression, and predominant proximal muscle involvement. The clinical picture and the morphological findings are compared with those previously described in a family. By immunofluorescence, all histologically abnormal muscle fibers, in particular those vacuolated, showed a strong deposition of the complement C5b-9 membrane attack complex over the whole muscle fiber surface. Weak immunostaining for membrane attack complex was also found in endomysial capillaries and perimysial vessel walls. Muscle fibers showed sarcolemmal immunolabeling with anti-major histocompatibility complex I, which was also present on the margins of many vacuoles. All vacuoles were stained by antidystrophin antibody, which colocalized in most of them with antilaminin immunostaining. Taken together, these results suggest that the deposition of membrane attack complex on the damaged cell surface membrane could be important in the pathogenesis of this muscle disorder, and that the membrane-bounded vacuoles could be a consequence of sarcolemmal invagination.

Abstract
Expression of NADPH-diaphorase (NADPH-d) was studied in the rat telencephalon and diencephalon from embryonic day 15 (E15) to postnatal day 30 (P30). The study has focused on the first appearance of NADPH-d staining in some areas which show high expression during adult life. The time of appearance ranged from E15 to the first days following birth, depending on the location of the cells. In many regions, neuronal processes, when staining appeared, were observed in close relationship with cerebral vessels. A possible role for nitric oxide in brain development should be explored.

Abstract
The aim of the experiment was to study the effects of stereotaxic lesions of the anterior and the posterior regions of the corticomedial amygdaloid nucleus (CMN) on the display of lordosis behavior by the male rat. Animals were orchidectomized as adults and given estradiol benzoate and progesterone (P) sequentially. Sexual behavior testing was performed by 9 +/- 1 hr after P injection. Lesions placed into the posterior region of the CMN significantly decreased the proportion of animals showing lordosis behavior as compared to sham-operated and control animals. By contrast lesions in the anterior region of the CMN did not cause any changes in the proportion of animals displaying lordosis but markedly increased the lordosis quotient (LQ) of responding animals. The CMN was then concluded to exert a dual control in the display of lordosis behavior in the male rat with a posterior region regulating the willingness of animals to display lordosis behavior and rostral region subserving inhibitory mechanisms related to the sexual performance (LQ values).

Abstract
Previous studies showed that different amygdaloid nuclei are involved in the control of lordosis behavior in female rats. The objective of the present study was to determine whether these nuclei played a role in the control of lordosis behavior in the male rat. Lesions were placed into different amygdaloid nuclei in male rats castrated as adults and primed with ovarian hormones. Lesions in the corticomedial amygdaloid nucleus completely suppressed lordosis behavior as expressed by the number of animals displaying lordosis responses to male mounts. By contrast extended lesions placed into the lateral amygdaloid nucleus (LN) remained without effects. Lesions placed in the very posterior part of the LN produced "hypersexuality" with a rise in the number of animals displaying lordosis responses and high LQ values. Lesions in the anterior part of the LN induced a decrease in the number of animals showing lordosis responses. The amygdala was then concluded to represent a functionally heterogeneous structure with different regions exerting opposite effects on the display of lordosis behavior in the male rat.

Abstract
Previous observations showed that exposure to the odor of male urine prior to mating could enhance the display of lordosis behavior in male rats feminized with ovarian hormones. This study was performed to determine in feminized male rats whether the control of lordosis behavior by the olfactory system was mediated by the ventromedial nucleus (VMN) of the hypothalamus. Male rats were orchidectomized (ORCH) as adults and primed with 25 micrograms estradiol benzoate (EB) and 150 micrograms progesterone (P) 40 hr apart. Lordosis behavior was tested 9 +/- 1 hr after P injection. VMN lesions were shown to completely suppress the display of lordosis behavior as compared to sham VMN operated and dorsomedial nucleus (DMN) lesioned animals. Exposure of feminized rats to the odor of male urine by 9 +/- 1 hr before mating significantly increased the proportion of ORCH rats that displayed lordosis behavior in response to male mounts. This effect was abolished by VMN lesions but was maintained in the sham VMN operated and DMN lesioned animals. These results were discussed in the light of the present knowledge on the neuroendocrine and olfactory structures which mediate lordosis behavior in the male rat.

Abstract
Small ventromedial nucleus lesions were placed in 4-day cyclic female rats in order to determine whether cycle lengthening - previously observed in some females following such lesions - could result from changes in follicular growth. A slowing up in follicle development was observed in lesioned females with a 24-hour cycle lengthening as compared to those with a maintained 4-day cyclicity. Similarly, natural 5-day cyclers displayed slower follicular growth than natural 4-day cyclers. A rebound effect in follicular growth was observed on proestrus in either natural or VMN lesioned 5-day cyclers compared to either natural or VMN lesioned 4-day cyclers. Concomitantly blood FSH level appeared to be higher on proestrus morning and afternoon in 5-day than in 4-day cyclers. The pattern of LH release differed between natural 4-day and natural 5-day cyclers on proestrus at 17:00-19:00 h. LH release appeared to be delayed by one hour in VMN lesioned rats with 24 hour cycle lengthening as compared to natural 5-day cyclers. The duration of LH release in VMN-lesioned rats with a maintained 4-day cyclicity was shorter than in natural 4-day cyclers.

Abstract
The mechanisms involved in the reduced cycle duration following exposure to the odour of urine were studied in natural and experimental 5-day cyclic female Wistar rats. A decrease in the rate of ovarian progesterone secretion from the morning of dioestrus I to that of dioestrus II was observed in females whose cycle duration was reduced from 5 to 4 days following exposure to the odour of rat urine. No decrease in ovarian progesterone secretion occurred in females maintaining a 5-day cyclicity despite exposure to this odour. An increase in follicular growth was noted in females with cycle duration reduced from 5 to 4 days, when compared with those maintaining a 5-day rhythm. As a result of exposure to the odour of urine no reduced cycle duration occurred in females with cycles lengthened from 4 to 5 days as a result of progesterone injection on dioestrus I of 4-day cycles. Hence the decrease in ovarian progesterone secretion, induced by exposure to the odour of urine, is considered to cause a speeding up in follicular growth, thereby reducing oestrous cycle duration in 5-day cyclic rats.

Abstract
Small bilateral lesions of the hypothalamic ventromedial nucleus (SVMN) were produced in 4 day cyclic female Wistar rats by passing a 2 mA cathodic current through stereotaxically oriented platinum unipolar electrodes for 7 sec. The 24 h lengthening of cycle which occurred in 111 our ot 208 females was shown to depend upon lesion placement. Early s.c. injection of 0.75 or 1.5 mg progesterone caused 24 h cycle prolongation more frequently in SVMN-lesioned females with maintained 4 day cycles than in 4 day cyclic unoperated, sham VMN-lesioned, or dorsomedial nucleus (DMN) lesioned females. This effect proved to be related to lesion placement. It was therefore concluded that the VMN is involved in the mechanisms whereby progesterone controls estrous cycle duration in the rat.
