WAY I LOVE PAKISTAN

I HAVE BEEN great for my country I have it for several different reasons first of all I was borm here it is my motherland I have passed all my life here so it natural for me to love my country

I HAVE been eating the tasty fruits of my country have been become strong because I have eaten its wheat and drunk its water I have taken the milk of its animals I have breathed in its air I love the beautiful flowers in bright colours I smell and observe I like the fine trees on the mountains and hills and in the gardens

I LOVE MY COUNTRY because I am a patriot a person who dose not love his country dose not deserve to live in it move all the places where I passed my childhood move the play grounds where I have played I like the streets in which I have played as a child the rods along which I have walked and run with other children

I HAVE BEEN LIVING with other Pakistanis I have studied and worked with them my friends are all Pakistanis I can only have feeling of love for them

MY COUNTRY IS like a small continent to its south is the sea whose waves strike against a long sea coast in Karachi you have moist climate as it is close to the sea in the inner parts of sind it is dry and hot as we have great deal of desert in baluchistan it is fry and cold in the Punjab it is neither so hot nor so cold parts of the N W F P  are like Eu

I LOVE PAKISTAN BECAUSE IT IS AN ISLAMIC COUNTRY I AM A MUSLIM AND LIKE TO live with muslims I love Pakistan from the hearts I shall always love my country

SEXUAL CYCLE IN MOSQUITO

Sexual life –cycle of plasmodium is completed in the gut of female Anopheles mosquito resulting in the infective sporozoites the cycle comprises of the following threr stages

[1]; GSMETOGONY; THE GAMOCYTES are taken up along with the blood into the stomach of the mosquito the female gamocytes soon become macrogemete which is ready to be fertillzed each male gamocyte forms 6 to 8 sperm-like microgametes by a process of exfagellation

[2]; SYNGAMY; THE TWO GAMETES of the opposite sexes fuse together to from a zygote the process is called syngamy the zygote become worm –like ookinete it penetrates the stomach wall to settle down just under the midgut here after absorbing the nutrients it become rounded and encycts to form the oocyst

[3]; sporogony; in 6 to 7 days the nuclieus of the oocyst divides into thousands of slender sporozoltes by the process of sporogony the cyst bursts and the liberated sporozoltes migrate towoeds the salivary glands where they await transfer to a human host

SYMPTOMS OF MALARIA;;;

THE SYMPTOMS OF MALARIA FIRST APPEAR AFTER SEVERAL DAYS OF INFACTION IN MAN THE TIME TAKEN BY THE PARASITS BEFORE IT APPEARS IN THE BLOODS IS CALLED INCUBATION PERIOD THE SYMPTOMS THAT APPEAR IN THE PERIOD OF INFACTION INCLUDE NEUSEA LOSS of appetite constipation and insomnia soon headache mascualar pains aches in the joints develps followeds by chills

AT the onset of malarial fever the patient suffers from shaking chills and sweating the body temperature many rise as 106f/

LIFE –CYCLE OF MALARIAL PARASTICE

LIFE –CYCLE of plasmodium is completed in two hosts man and female anopheles mosquito Man serves as primary host whereas mosquito serves as secondary host the parasite completes its life cycle in two main phases[ A] asexualcycle in man and [B] sexual cycle in mosquito

ASEXUAL CYCLE IN MAN – SCHIZ OGONY

A healthy person acquires infection when a female anopheles mosquito containing infective [SPOROZOITES]of the parasite its salivary glands bites him for sucking his blood schizogony comprises of the following phases

[1] PER-ERYTHROCYTIC PHASE

ONCE WITHIN THE HUMAN BLOODS THE SPOROZOITES circulate for about half an hour and then get into the liver to invade the hepatic cells after penetrating the hepatic cells each sporozoite grows for number of days and become a schizont it divides to from a large number of uninucleate CRYPOZOITAN these are liberated when the liver cell bursts the cryptozoites invade fresh liver cells and multiply producing enormous numbers of METACRYPTOZOITES this phase is referred to as per-erythrocytic phase

ERYTHROCYTIC PHASE

[the metacryptozoites after escaping into the blood stream invade the red blood corpuscles each becomes rounded and is salled TROPHOZOITEC when it grows in size the nucleus is pushed to one side into the peripheral cytoplasm it resemblies a signet ring and is referred to as signet ring stage the TROPHOZOITE ingests a large amount of cytoplasm of the R.B.C. THE blood haemogobin is broken down into its protein component which is used by the trophozoite it develops into an active amoebo;d trophozoite after active feeding become rounded grows in size and become a SCHIZONT it now undergoes schizogony and produces MEROZOITES with the rupture of                  R.B.C.the merozoites are liberated and blood complete into the blood plasma these invade fresh corpuscies to repae the cycle the time taken to complete one erythrocytic cycle depands upon the spectes of plasmodium

[3] POST –ERYTHROCYTICPHASE

some merozoites produced in erythrocytic phase reach the liver cells and undergo schizonic development this is known as post erythroccytic phase

[4] GAMOGONY

WHEN successful asexual multiplication is achieved the merozoites do not proceed further with the erythrocytic phase but after entering the R.B.C. increase in size to become gamocytic male microgamocytes amd female macrogamocytic the gamocytes do not divide .but remain within their host blood until they ingested by the vendor in which they continue their development
