I have read with interest Doctors Adams' and El-Salawy's comments on my case report identified in their letter as the "Lausanne baby." I do think that the "Lausanne baby" represents a case of pulmonary vascular sequestration inasmuch as the inferior lobe of the left lung received its blood supply by means of three arterial branches coming off directly from the aorta. On the other hand, I do not think that the "Lausanne baby" is a case of pulmonary parenchymal sequestration and this because the inferior lobe of the left lung was proven to be, at least to my satisfaction, in direct communication with the remainder of the respiratory tract.

The local isometric endurance of the elbow flexors of four groups of five female subjects was tested. Two groups had the circulation to the contracting muscles occluded by a pressure cuff and the others had normal circulations. One group in each of the open and occluded conditions worked with a load equivalent to one-third of maximum strength and the other group worked against a resistance of two-thirds of maximum strength. The endurances of the two groups working with two-thirds of maximum strength as load were not significantly different despite the occlusion of the blood supply in one of the groups. The endurance of the group with open circulation and one-third of maximum strength as load was significantly greater than that of the group with the same load but with occluded blood supply. Only at this lower level of loading did the artificial occlusion of the blood supply to the active muscle group appear to reduce its endurance. Submitted on October 19, 1962

The extraosseous and intraosseous vascularity of the talus was studied in 26 fresh cadaver limbs. The specimens were injected with latex or Batson's compound, debrided by a nondissection technique, and cleared by a modified Spalteholz method. The extraosseous vascularity was through the branches of the three major regional arteries which entered the five nonarticulating surfaces of the bone. The major blood supply to the body was provided by the artery of the tarsal canal. The deltoid and sinus tarsi vessels provided significant minor sources of vascularity. The superior neck and posterior tubercle vessels supplied small areas of the body, but did have anastomoses with the other arteries in some specimens. These vascular patterns correlated well with the reported incidence of avascular necrosis of the body of the talus following injury.

Angiogenesis is a term that describes the formation of new blood and lymphatic vessels from a pre-existing vasculature. This allows tumour cells to acquire sustenance in the form of nutrients and oxygen and the ability to evacuate metabolic waste. As one of the hallmarks of cancer, angiogenesis has been studied extensively in animal and human models to enable better understanding of cancer biology and the development of new anti-cancer treatments. Angiogenesis plays a crucial role in the process of tumour genesis, because solid tumour need a blood supply if they are to grow beyond a few millimeters in size. On the other hand, there is growing evidence that some solid tumour exploit existing normal blood supply and do not require a new vessel formation to grow and to undergo metastasis. This review of the literature will present the current understanding of this intricate process and the latest advances in the use of angiogenesis-targeting therapies in the fight against cancer.

1. Dogs whose splenic veins or portal vein (Eck fistula) have been transplanted into the inferior vena cava, or whose splenic veins have been ligated, show a lessened tendency to jaundice similar to that exhibited by splenectomized animals. 2. Although the previously existing anemia and the concomitant increased resistance of the red cells of these animals are undoubtedly factors in the greater resistance to hemolytic agents, the lessened tendency to jaundice is, in part at least, due to a mechanical factor dependent on the course of the blood supply to the liver. 3. The additional anemia caused in the test animals by hemolytic agents is usually less than in the controls, although the total fall from the original normal may be greater. This applies to the splenectomized as well as the other test animals and is a modification of our former statements in regard to the severity of the anemia in splenectomized dogs. 4. Although the destruction of blood in these animals is less than in the normal controls, the repair of the same takes considerably longer than in the controls. This confirms similar results previously obtained in splenectomized animals. 5. The white cells exhibit much the same changes as they do following the administration of hemolytic agents to splenectomized or normal animals. As these changes are not unlike those following uncomplicated splenectomy or the operations here discussed, they cannot be considered as characteristic of any of the above procedures, but perhaps as an accompaniment of any temporary increased blood destruction. 6. The reaction of test and control animals is substantially the same, whether the jaundice is caused by toluylenediamin or hemolytic immune serum.

Experiments of this study indicate that the kidney does not normally autoregulate its blood flow; in these experiments a change in perfusion pressure always resulted in a corresponding change in renal blood flow when the kidney was not subjected to surgical trauma. On the other hand, when renal ischemia was induced or when the perirenal tissues were intentionally damaged, autoregulation of renal blood flow occurred in every instance. Two possible theories are discussed for this autoregulation: a) blockage of the renal lymphatic drainage and b) disruption of the blood supply to the walls of the renal and intrarenal arteries.

Vata Vyadhi is considered one among the Ashta Maha Gada as told by Acharya’s. Out of all Nanatmaja Vata Vyadhis, the disease Pakshaghata is considered superior among the other Vataja disorders. In modern era, the Lakshana’s of Pakshaghata is closely resembles the disease Hemiplegia. In Hemiplegia, symptoms appears due to the Ischemia of Brain tissue which is an end result of improper blood supply to the brain either due to thrombus, embolism or may be due to rupture of any cerebral blood vessels. Acharya Bhela, has considered Pakshaghata as one among the Asthi Majjagata Roga’s. Acharya Sushruta also states that, the Mastulunga Majja is nothing but it is Majjadhara Kala. So, here an attempt has been made to evaluate the efficacy of Brimhana Nasya along with Shamanoushadi’s for the management of Pakashaghata.

Vascularized perichondrium and periosteum are potentially ideal grafts for airway reconstruction. We quantitatively evaluated the effect of a 2-hour interruption of blood supply on subsequent growth of cartilage from vascularized auricular perichondrium grafted in the rabbit airway. Two pedicled auricular perichondrocutaneous flaps were elevated and used to repair two small anterior airway defects in each animal (n = 17). One of the two flaps was randomly clamped for a 2-hour period during the operation, with the other flap serving as a paired control. We found no significant difference in chondrogenesis between the two groups. Our findings support the use of perichondrium and periosteum as free revascularized grafts for airway reconstruction.

About almost 5- 6% of men who had vasectomy surgery come back to doctors for its reversal in the form of microsurgical vasovasostomy or simplified Loupe Assisted vasovasostomy. Vasovasostomy is a technique which is used to regain fertility in men. This technique, over the years, has gone through many advancements with better results, including one layer, two layers and now three layers microsurgery with equipments and techniques to form a meticulous anastomosis. While, on the other hand, simple Loupe Assisted technique is done using Prolene Stent. During vasovasosotomy it is extremely important to maintain normal blood supply to the tissues and muscle to build a tension free anastomosis. In this modern age of in vitro fertilization (IVF) and intracytoplasmic sperm injection (ICSI), it has become immensely important to clearly identify the outcomes of both the surgery procedures to void future issues after vasectomy reversal. Little data is present in comparison of the outcomes of both the vasectomy reversal methods. Therefore, this paper is compiled up to throw some light on case studies to better evaluate the best methods of reversal. A study was carried out in the hospital of bahawalpur from January 2017 to January 2019.
