The cambium which remains between the xylem and the phloem in the vascular bundles is called a order kamagra soft 100 mg. The cells of the vascular cambial ring which are cut off towards the outer side get differentiated into a purchase kamagra soft 100 mg. The protective layer developed during the secondary growth of the stem is called a order kamagra soft 100 mg otc. Ground plan or a sector enlarged is to be drawn, no need to draw both the diagrams. Now, we shall study how characters and traits are inherited from one generation to another. Sexual reproduction, besides producing individuals, introduces variability in the offspring by combining traits of parents. Now, we know that the units of heredity are genes that are transmitted from one generation to another. The genes are arranged in a linear manner at specific positions on specific chromosomes. Differences in gene expression are the basis for differentiation of the organisms. Bridges in 1916 was the first to prove that the genes are carried on the chromosome. Structure of chromosome Each chromosome consists of similar structures called chromatids. There are two types of constrictions Secondary constriction namely primary constriction and Kinetochore secondary constriction. Satellite The primary constriction is Secondary constriction made up of centromere and kinetochore. If the centromere of the chromosomes is damaged, such chromosome fails to move at anaphase. The monocentric 110 chromosome has one centromere and the polycentric chromosome has many centromeres. The kinetochore is made up of protein fibres and microtubules which assist in the formation of spindles during mitosis and meiosis. In a given set of chromosomes only one or two chromosomes have secondary constrictions. The nucleoli develop from secondary constrictions and such secondary constrictions are called nucleolar organisers. A satellite is a short chromosomal segment and separated from the main chromosome by a relatively elongated secondary constriction. According to the position of centromere, Centromere Arm Telocentric Acrocentric Sub-metacentric Metacentric Fig. In the human diploid cell, 44 chromosomes are autosomes whereas the rest two are sex chromosomes. Sex chromosomes In the diploid cells of animals and certain plants, one or more special chromosomes are different from the autosomes in their morphological structures and behaviour. Special types of chromosomes In Eukaryotic organisms certain chromosomes are found only in certain special tissues and are not seen in other tissues. There are two types of giant chromosomes polytene chromosome and lamp brush chromosome. The characteristic feature of polytene 112 chromosome is that along the Chromosomal puff length of the chromosome there is a series of dark bands alternate with clear zones called Dark band inter bands. The polytene inter band Polytene chromosome chromosome has extremely large puff called Balbiani ring. As this chromosome occurs in the Lateral Loop salivary gland it is known as salivary gland chromosomes. They occur at the diplotene stage of meiotic prophase in oocytes of an animal Salamandor and in giant nucleus of the unicellular alga Acetabularia. Gene is also defined as a nucleotide sequence that is responsible for the production of a specific protein. When a gene undergoes changes due to mutation, it results in biological variations. They conducted bio-chemical research on the fungus Neurospora and concluded that the major role of genes was to carry information for the production of enzymes. Now, the hypothesis has been modified to one gene one polypeptide hypothesis because the product of gene action is always a polypeptide. Each species has a characteristic number of chromosomes in the nuclei of its gametes and somatic cells. The gametic chromosome number constitutes a basic set of chromosomes of the organism.

Ophioglossum 631 114 The genome size of an individual is expressed in terms of number of base pairs either in kilobases (1000 bp) or in megabases (one million bp).

Contact tracing in poor-resource fragmentation of muscle and elastic tissue, and similar environments is a pipe-dream, and therefore recurrence by fragmentation in the internal elastic lamina of the intima, reinfection is frequent. Thrombosis may also occur in mesenteric vessels, or cerebral arteries resulting in a cerebro-vascular accident. Aneurysms tend to occur in the carotid and superficial femoral arteries, although any artery may be involved and multiple lesions are seen. Deep vein thrombosis occurs with 10 times greater frequency, though you will detect less than 1% of cases clinically. Risks of surgery are obviously further increased when you take this statistic into consideration, especially as you can use prophylactic anticoagulants only with reluctance in the presence of thrombocytopenia. The larger the implant, the bigger the problem: bone infections then often fail to respond to antibiotics, removal of the implant, debridement and subsequent sequestrectomy.

Suggesting tuberculosis of the hip: a chronic history and radiograph signs of tuberculosis (5 buy cheap kamagra soft 100mg line. Suggesting a tuberculous psoas abscess arising from the spine: a chronic history best kamagra soft 100 mg, radiographic changes in the spine purchase kamagra soft 100 mg visa. A psoas abscess does not usually need drainage, unless it is very large and causing pain. It will resolve slowly on therapy for tuberculosis; incising it can lead to secondary infection. Suggesting acute and usually staphylococcal osteomyelitis of the spine (uncommon): more pain, spasm of the sacrospinalis, radiographic signs in the spine. Feel the exact site of the mass and its consistency and boundaries, and feel for fluctuation. A, typically the hip more flexed than is shown adenitis with periadenitis and without pus formation does here. Suggesting iliac adenitis with periadenitis or an The abscess will have pushed the peritoneal lining of the abscess: a septic lesion on the skin which may be minimal right iliac fossa medially and superiorly. Make an incision and have healed (adenitis may appear 2wks after the 5-10cm or more over the swelling about 2cm above primary lesion has settled), a markedly flexed hip with a the inguinal ligament, starting just medial to the short history, a mass in the groin or right iliac fossa just antero-superior iliac spine (6-12D). Take a long haemostat above the inguinal ligament, no pain when you percuss the and push this through the muscle over the abscess until greater trochanter; you can flex the hip a bit more, no you find pus. Then, using your fingers, enlarge the spasm of the sacrospinalis, and no radiographic changes. Suggesting pyomyositis of the iliopsoas: the same signs If the leg remains in spasm, apply traction as above. Draining an iliac abscess is potentially impossible, and is not important because the treatment is dangerous: you may injure the caecum or the iliac vessels. An anorectal abscess usually originates in an anal gland, and may communicate through a tiny opening with the A perianal abscess presents as a red tender swelling close anal canal, at the pectinate line. On rectal examination, there is little or no skin and the anus (a fistula) is the reason why about half of tenderness, induration, or bulging in the anal canal. Most abscesses settle by An ischiorectal abscess lies deeper than a perianal one, discharging spontaneously, or being drained, but a serious is larger and further from the anus; it forms a deep tender life-threatening infection can sometimes spread in the soft brawny swelling and is not fluctuant until late. Presentation is usually acute because the pain is intense: On rectal examination you may feel a tender induration severe throbbing pain keeps the patient awake at night. The infection On examination, you find a tense tender swelling near the may spread posteriorly and then to the other side as a anus. Sometimes, there may be little to see and no horseshoe abscess, so that there now are signs on both fluctuation to feel, except mild tenderness at the anal sides. If the pain suddenly resolves, the abscess has probably A submucous or high intermuscular abscess (rare) spontaneously ruptured. But there may now be a presents with pain in the rectum and no external swelling, persistently discharging sinus or fistula opening on to the unless it is complicated by an ischiorectal or perianal skin near the anus. On rectal examination you may be able to feel a soft, diffuse, tender swelling extending upwards from the pectinate line. A pelvirectal abscess (rare) presents with fever, but no local anal or rectal signs. With your finger in the anus, you may be able to feel fluctuation above and lateral to the anorectal ring. Do not delay treatment in the hope that an anorectal abscess will cure itself: always incise it. A large incision will not necessarily give a better result; recurrence depends on whether or not there is a tiny communication between the abscess and the anal canal. As anal glands are mostly posterior, most abscesses and most fistulae are posterior. These glands extend into the sphincters, so that pus can track in various directions: (1) downwards to cause a perianal abscess; (2);laterally, through the sphincters, to cause an ischiorectal abscess. The ischiorectal spaces connect with one another behind the anus, so that infection on one side can spread to the other side (horseshoe abscess); (3);rarely, medially under the mucosa of the anal canal to Fig. If you probe unwisely, you may create an abscess over its most prominent or fluctuant part. Do not break down any natural barriers to (3) If an abscess lies anteriorly, consider the possibility the spread of infection.
