using System.Collections;

public class EnemyDamage : MonoBehaviour 
{
void  OnCollisionStay ( Collision hit  )
	{
	if(hit.gameObject.tag == "EnemyDamage")
	{
	GUIHealth.HITS -= 1;
	}
}
}
using UnityEngine;
using System.Collections;

public class PlayerFallout : MonoBehaviour {
static int dead= false;

void  OnTriggerEnter (  Collider hit   ){
    if(hit.gameObject.tag == "Fallout")
    {
		dead = true;
    }
}

void  LateUpdate (){
      if(dead)
      {
	  GUIHealth.HITS = 500;
     Application.LoadLevel (Application.loadedLevelName);
	 dead = false;
      }
}
}
using UnityEngine;
using System.Collections;

public class GUIHealth : MonoBehaviour {
		Texture2D Health00;
		Texture2D Health10;
		Texture2D Health20;
		Texture2D Health30;
		Texture2D Health40;
		Texture2D Health50;
		Texture2D Health60;
		Texture2D Health70;
		Texture2D Health80;
		Texture2D Health90;
		Texture2D Health100;
		
		static FIXME_VAR_TYPE HITS= 500;
		
		void  Update ()
	{
			print("Hits: "+HITS);
			
		FIXME_VAR_TYPE heathtexture= gameObject.Find("Health100");
		
		if (HITS < 500)
		{
			guiTexture.texture = Health90;
		}
				if (HITS < 450)
		{
			guiTexture.texture = Health80;
		}
				if (HITS < 400)
		{
			guiTexture.texture = Health70;
		}
				if (HITS < 350)
		{
			guiTexture.texture = Health60;
		}
				if (HITS < 300)
		{
			guiTexture.texture = Health50;
		}
				if (HITS < 250)
		{
			guiTexture.texture = Health40;
		}
				if (HITS < 200)
		{
			guiTexture.texture = Health30;
		}
				if (HITS < 150)
		{
			guiTexture.texture = Health20;
		}
				if (HITS < 100)
		{
			guiTexture.texture = Health10;
		}
				if (HITS < 50)
		{
						PlayerFallout.dead = true;
						GUIHealth.HITS = 500;
		}
		}
		
	
	void  gotHit (){
	HITS -=1;
	}
}

Thank you for your time.

One thing I can suggest you is made your static variables public, because they are not public by default in C#. Your access to GUIHealth.HIT will not be possible without the public keyword, depending on your file structure inside the project.
