The authors give an annotated list of venomous Invertebrates occurring off Tunisian seas. They point out the action of their venom, the injuries about man, and different therapeutic and prophylactic methods. They conclude that the Cnidaria are the most abundant and most dangerous.
The authors present some eatable benthic Invertebrates like Muricidae and chiefly Mytilidae which could become poisonous under the action of biological et physical and chemical factors of the environment. The symptoms caused by poisonings due to ingestion of contaminated shells are described and therapeutic and prophylactic methods are proposed.
The authors point out three cases of appendicular taeniasis disease into an analytical retrospective study of 5,000 appendicectomies. In these 3 cases the parasite does not induce important processes level with the appendix. The localisation of the parasite is very rare.
After anatomo-pathologic, épidemiologic and etiopathogenic description of canine Mast-cell tumor, the authors insist on the importance of this neoplasm in comparative pathology. Such animal model observation can be eventually used both in cancer Research and in allergo-dermatology.
Study of the histology, epidemiology and course of 106 non-Hodgkins malignant lymphomas of the digestive tract seen in Tunisia revealed the high incidence of these ML in comparison with other malignant tumours of the same site and their predominance above all in young male subjects. The classification of these lymphomas has shown that forms with a high degree of malignancy are seen much more often than forms with a low degree of malignancy: Centroblastic ML accounted for more than 50 p. 100 of the histological forms seen in the intestine. Intermediate centroblastic and immunoblastic ML predominated in the stomach. Nodular ML is very rare. Finally, an important feature in the course of these tumours is worthy of note, i.e. the prolonged survival of 9 of our patients. This survival would however appear to be related more to the stage of the disease than to the histological type and the nature of the treatment used.
The inshore waters of Northern and Southern suburbs of Tunis are chiefly polluted aroud urban cities. The pollution increases with temperature, men (touristes and bathers), the actions of wind and currentology.
The authors describe an hermaphrodite Scyliorhinus stellaris with both complete but juvenile male and female genital apparatus.

The study to an analyse of 726 samples of sea water, taken monthly (1977-1978) at 23 stations. At the basis of the data concerning the NPP of total coliformas, 75,5% of the samples point out a clean water for the bathing place, 11,04% = "acceptable" and 9,96% = "dirty". Considering the data about the MPP of fecal coliformas and of fecal streptocques, the sanitary state is reported in 94,23% "clean for the bathing place", 1,77% "acceptable" and 4% dirty.
The authors describe an epigeal winter seasonal biotope of "culex pipiens autogenicus. The biotope consists of the irrigation system of the large Bervedere park of Tunis city. During the cold and rainy season the irrigation system is abandoned. Many water pools are formed in it in which C. pipiens and Culiseta longiareolata multiply. In summer the operation of the irrigation system brings about the disparition of the nests of larvae. Breeding performed from larvae collected in nature pointed out the autogenous and stenogam characters. Morphologically the specimens correspond to autogenous forms. The importance of the investigations is the evolution of the C. pipiens autogenic species in external nests of larvae during winter was pointed out.
The authors do a clinical anatomic study showing 102 cases of lung primitives cancers to be diagnose in 60% cases on biopsy and 40% on operation'piece. The matter in boundless majority of cases is carcinoma 92%, themselves overlooked by squamous cells carcinoma 55%, forwarded by adenocarcinoma 20%, small cells carcinoma represent 11% of cases and large cells carcinoma 7%. The mean age of occur is 55 years and any cases of carcinoma is observed at persons under 30 years of age. 94% of person are masculine. The majority of tumors 58% cases present themselves as bulky masses exceeding 6 cm of diameter. The authors insist in this study on necessity of early diagnosis when the therapeutic will be curative.
The authors present 16 cases of malignant ovarian tumors in childhood, censed in Pasteur Institute - Tunis. These tumors are scarce, and present in the literature only 3% of the malignant tumors in childhood. In this series, germ cell tumors are the most frequent and present 81.25% of these cases, of which 43.75% of dysgerminoma. Gonadal stromal tumors are more scarce (6.25%). The prognosis of these tumors was transformed by the radiation therapy in dysgerminoma, and the chemotherapy in the other germ cell tumors. These tumors must be diagnosed and treated early.
