Malignant Lesions

Ovarian carcinoma is the second most common carcinoma of the female reproductive system .It is the leading cause of death from gynaecological malignancy .The purpose of this study is to observe the clinicopathological spectrum of ovarian neoplasms with the expression of ER and PR in the different malignant lesions .A total of 156 cases of ovarian tumours were included in this study, and surface epithelial tumours were found to be the commonest neoplasm followed by germ cell tumours. Expression of ER and PR was found to be highest in Serous and Endometrioid tumours. PR Negative cases showed a higher grade and stage.

In a preliminary communication on the development of mouse chimaerae formed from fused eggs (Tarkowski, 1961) three cases of intersexuality were reported among newborn animals. Sexing was based exclusively on macroscopic examination of the reproductive system. The present paper deals with the microscopic structure of this system in chimaeric hermaphrodites, with special reference to the structure of the gonads. The occurrence of intersexes among animals developed from fused eggs was considered as one of the proofs of their chimaeric constitution (Tarkowski, 1961). Abnormalities similar to those displayed by these chimaerae have been described in the mouse and related rodents in sporadic spontaneous cases of hermaphroditism. However, while the genesis of the latter is unknown, there are strong indications that hermaphroditism among chimaerae develops on the basis of sex-chromosome mosaicism. This type of mosaicism can be expected a priori to occur in a number of individuals developed from two eggs randomly selected.

1. The structure of the male reproductive system of Carcinus is described with special reference to the region of formation of the spermatophores and the anatomy of the intromittent organ. 2. The vas deferens produces two fluids, one of these is probably chitin in a fluid form, whilst the other is similar in some respects to the substance forming the general body cuticle, i.e. protein. This substance forms the capsule of the spermatophore. 3. The intromittent organ consists of the modified first and second pleopods and is richly supplied with rosette glands similar to those producing the body cuticle. The ducts of these glands open into the cavity of the first pleopod and their secretion could easily pass with the seminal fluid into the female crab. 4. The female reproductive system is described with special reference to the spermatheca and the cyclical changes occurring in this organ. 5. The sperm plug is composed of two parts distinguishable by their staining reactions. One is similar to the cuticle in its general properties and is probably the product of the rosette glands in the male pleopod. The other is probably chitin formed from its fluid precursor in the seminal fluid of the male crab. 6. It is suggested that the spermatophore of the Brachyura is a degenerate structure having lost its main function, the protection of the sperms during the interval between copulation and egg-laying, in correlation with the development of the internal spermatheca and internal fertilization.

Tabular Form

The object of the present paper is to put upon record for the guinea-pig data which I have collected regarding (1) the relation between the number of young in a litter and the number of corpora lutea of pregnancy in the ovaries, (2) the distribution of corpora lutea between the two ovaries in two successive ovulations, and (3) the utilisation of the uterine horns in successive pregnancies. The data were obtained in the course of other researches and are arranged in tabular form (Tables I and II). The records from which they have been collected refer to 40 female guinea-pigs killed post partum, of which 16 were pregnant and 24 had not been reimpregnated. The size of the previous litter is known for 38 of these females; both ovaries were serially sectioned at 10 microns in the 40 animals, but in 4 the records of only one ovary were preserved.
